Add message for failed fountain monster detection
When the fountain quaffing monster detection effect was triggered on a
level without any monsters, no message would be printed. I think this
was the only scenario where drinking from a fountain wouldn't print
anything, so it stood out as unusual.
Print a messsage in the case monster detection fails, to make it
consistent with other fountain effects and ensure it's clear the hero
did still drink from the fountain on that turn. I used "the water
tastes like nothing" for the (sort of tenuous) connection to there being
nothing living on the level, but there might be a better message to put
in there.
Make sure xstart and ystart are always zero when not in_mklev
Running #wizloadlua to run Lua scripts that use coordinates in any way
would work differently if you were on certain levels for the first time
versus leaving and returning to them. This is because various bits of
level creation routines can leave xstart and ystart set to non-zero
values, which are then zeroed at some point when leaving and returning
to the level.
Since xstart and ystart are only relevant to level creation and lua
commands, this fixes the problem by zeroing them after leaving mklev
routines. (Saving them with the level doesn't work because xstart and
ystart are relative to the last used des.map, of which there could be
multiple, e.g. in Asmodeus's level or if two map-based themed rooms
happen to generate. I can envision a more complex solution in which
every des.map used in the level can be associated with an identifier,
whose xstart and ystart are saved for use by later post-level-creation
lua scripts, but currently I just want to make them consistent between
level visits.)
Fix: monster gender could not actually be specified in lua files
Noticed when I tried to create a male monster of a species that permits
both males and females (i.e. not a single-gender or neuter species),
half the time the monster ended up female anyway. This was because
get_table_montype picks a random monster gender for such species, and
lspo_monster just sets it to that, making it impossible to deliberately
have a monster of a certain gender.
This fixes that by defaulting the "female" table argument to random
instead of false, and then checking to see whether the level file set it
to something other than random. If so, it uses that value.
I debated whether this should allow a level designer to make a monster
of a gender that conflicts with their species, such as a male nymph, but
erred on the side of respecting the species. So attempting to specify a
male nymph, etc. will still result in a female one.
I was looking into "The Lord Surtur's corpse" and got side-tracked by
something else: move a priest hack for avoiding "aligned" in a corpse
description from corpse_xname() to obj_pmname(). The old variation
always picked "priest corpse" over "priestess corpse". The new one
will use either one of those if the corpse is flagged as such, or use
"cleric corpse" (avoiding "aligned cleric corpse") if it's flagged as
random.
Hide 'altkeyhandling' from the 'O' menu for !WIN32 builds. If
present in run-time config file it will be parsed and then ignored.
Instead of showing "unknown" for the value of the 'hilite_status'
compound option, show "none" if there are no highlighting rules, or
a pointer to other option "status highlight rules" when there are.
Deal with a few function parameters that are used for some
combination of build-time config settings and unused for others.
Remove redundant 'if (K)' from there_cmd_menu(). The !K case doesn't
get there and that test's presence fools the compiler (oldish clang)
into warning that 'npick' might be used uninitialized.
Change 'O's sub-menu for selecting new msg_window option setting to
work similar to the one for menustyle: show a description of what
the values mean with a two-line, two-column menu entry. Also make
its current value be pre-selected.
msg_window is a bit more complicated than menustyle because only
some interfaces support it and curses only supports two of the four
choices. It currently has one hard-coded reference to "^P" (in the
tty-specific 'combination' choice). Changing that is feasible but
seems like more trouble than it'd be worth.
Implement the suggestion by entrez to avoid "while helpless" in the
reason for the second death if hero gets killed, life-saved, and
killed again at the same time. Life saving sets 'multi' to -1 which
prevents the hero from moving again until next turn and is intended
to make the sequencing of "you survived that attempt on your life"
work if you're being interrupted during some multi-turn activity.
It used to behave differently when the first death occurred while
engaged in some voluntary multi-turn activity. I've removed that
because I couldn't figure out why; it might need to be put back.

fix #K3564 - obj sanity failure: N globs for N>1
Using #name and picking an item on the floor to be assigned a type
name allowed any of the four types of globs to be named. After
that, wishing for those by the assigned name bypassed the code that
forced the quantity to stay at 1. Asking for "3 foo" could then
produce "3 small globs of gray ooze" which fails obj_sanity() and
issues an impossible warning (which the fuzzer escalates to panic).
The "getobj refactor" patch changed the return value of call_ok().
When it gets used to check whether an object on the floor could have
a type name assigned (rather than as a getobj() callback), the test
that should have rejected the naming attempt accepted it instead.
Update the wishing code to handle globs differently: you can still
specify the relative size via small, medium, large, or very large,
but now you can specify a count either instead or in addition. A
count of more than 1 is used to multiply the created glob's weight,
although it's less likely to be honored as-is when the size is bigger
than small. Quantity is always forced to 1, at a different place in

Fix travel getting stuck oscillating between two locations
There's been occasional reports (perhaps once or twice a year)
of travel getting stuck moving repeatedly between two locations
next to each other, but it has never been reproduced before.
This special level lua code fragment is a minimal test case
which triggers it:
--- special level lua fragment, indented
des.map([[
--##---
###----
#-+----
####--L
]]);
des.door("open", 2,2)
--- end of special level lua fragment
The open door is required.
Magic map the level. Start from somewhere NW of the door, and try
to travel to the lava pool. Hero will get stuck oscillating between NW
of the door and two steps west of the door.
Here are the maps of the travel[][] array values from findtravelpath()
in those two steps in the above map:
There are two possible closest locations to the lava pool,
the one marked with "3" on the left map, and "4" on the right map.
Based on that alone, both would be valid places to path to.
But, in the left case, hero could not see the bottom location, so
the code won't even consider pathing to it, so it will start moving
towards the "3".
When hero moves to the second position, in the right map, now the "4"
could be seen. Now there are two possible closest locations we could
choose from. The code that scans the possible locations goes from top-left
to bottom-right, first going down (y-axis). So, the code sees the
"2" on the right. distmin() to there is 2. Good, we pick that location
to path to. Next, going down, the code considers the "4" ... which is
also equally close to the lava pool. and distmin does not consider terrain,
so ignores the door, so it has the same distmin value of "2", so the
code picks this location.
But: this was just a guess, because there's no known valid path to the
lava pool. The code loops back up to rebuild the travel[][] array
with a new starting location as the "4" from the right map, pathing
back to hero.
This is that travel array map:
-------------
| . . . . |
| 4 @ 3 . |
| 3 . 2 . |
| 3 2 1 x |
-------------
The way travelstepx and travelstepy arrays are built means that the first
location that considers the hero's location is the "3" SW of hero, so
hero will move there next. Repeat from beginning. If there was no door,
the travelsteps would reach hero's location first from SE.
(I left the travel[][] array rebuild and travelstepx/travelstrepy build
off from the other movement position, as it's not relevant)
The fix: When considering which of the two possible closest places to the
lava pool to path to, use the one with the lowest value in the travel array.
That value is the real number of moves it takes for the hero to walk there,
so the code will consistently path to the upper location, as it is "2",
instead of considering the "4" below it.
Also some minor code reorg, so it considers couldsee first instead of
later in two separate places.

stoning resistance revisited
It turns out that there were a bunch more monsters with the corpse-
conveys-stoning-resistance flag than just green mold. Instead of
stripping it off, give them (including green mold) a chance to confer
timed resistance against stoning and also against acid.
All of these can convey either of those two resistances. Like other
intrinsics obtained via eating, at most one can be obtained from any
given corpse.
green mold, acid blob, spotted jelly, ochre jelly, black naga,
yellow dragon, Chromatic Dragon
These can confer temporary stoning resistance but not acid resistance:
lizard, chickatrice, cockatrice, gargoyle, winged gargoyle,
xorn, Medusa
There aren't any that confer just acid resistance without a chance for
stoning resistance.
The effect lasts for 3d6 turns, or is extended by 3d6 more if randomly
chosen and applied when already in effect.
Having temporary acid resistance time out during another meal when
eating a corpse that ends up conferring acid resistance seems strange.
The protection against acid is granted at the start of the meal and
continues to the end (in regards to eating, not external attacks) even
when the intrinisic is lost in between. I'm not sure whether that
needs some form of fixing, and if so, what that fixing should be.

each of the styles. Makes the menu entries two lines of two columns
each: first line contains the setting value and the first half of
its description; second line has blank left column and second half
of description in the right one. Value on first line and single-line
description on second would have been simpler but this seems easier
to read--the four possible values don't have any clutter between them.
