mergetool.prompt used to default to 'true', always causing a confirmation
"do you really want to run the tool on this path" to be shown.
Among the two purposes the prompt serves, ignore the use case to
confirm that the user wants to view particular path with the named
tool, and make the prompt only to confirm the choice of the tool
made by autodetection and defaulting. For those who configured the
tool explicitly, the prompt shown for the latter purpose is simply
annoying.
Strictly speaking, this is a backward incompatible change and the
users need to explicitly set the variable to 'true' if they want to
resurrect the now-ignored use case.

These were originally removed by 0232852 (t5537: move

accidentally re-added in 1ddb4d7 (Merge branch

This looks like an error in manual conflict resolution.
Here's what happened:
1. v1.9.0 shipped with the http tests in t5537.
2. We realized that this caused problems, and built 0232852 on top to move the tests to their own file.
This fix made it into v1.9.1.
3. We later had another fix in nd/upload-pack-shallow that
also touched t5537. It was built directly on v1.9.0.
When we merged nd/upload-pack-shallow to master, we got a
conflict; it was built on a version with the http tests, but
we had since removed them. The correct resolution was to
drop the http tests and keep the new ones, but instead we
kept everything.

false when the major version changes, which is not what we want here.
Fix that for both places where the git version is checked using vsatisfies

change of the major version is not considered to be a problem, as long as
the new major version is larger. This is done for both the place that

Fix a buffer over-stepping issue triggered by providing an absolute path
that is similar to the work tree path.
abspath_part_inside_repo() may currently increment the path pointer by
offset_1st_component() + wtlen, which is too much, since
offset_1st_component() is a subset of wtlen.
For the *nix-style prefix '/', this does (by luck) not cause any issues,
since offset_1st_component() is 1 and there will always be a '/' or '\0'
that can "absorb" this.
In the case of DOS-style prefixes though, the offset_1st_component() is
3 and this can potentially over-step the string buffer. For example if
work_tree = "c:/r"
path = "c:/rl"
Then wtlen is 4, and incrementing the path pointer by (3 + 4) would
end up 2 bytes outside a string buffer of length 6.
Similarly if
work_tree = "c:/r"
path = "c:/rl/d/a"
Then (since the loop starts by also incrementing the pointer one step),
this would mean that the function would miss checking if "c:/rl/d" could
be the work_tree, arguably this is unlikely though, since it would only
be possible with symlinks on windows.
Fix this by simply avoiding to increment by offset_1st_component() and
wtlen at the same time.

blame: fix broken time_buf paddings in relative timestamp
Command `git blame --date relative` aligns the date field with a
fixed-width (defined by blame_date_width), and if time_str is shorter
than that, it adds spaces for padding. But there are two bugs in the
following codes:
1. The type of blame_date_width is size_t, which is unsigned. If
time_len is greater than blame_date_width, the result of
"blame_date_width - time_len" will never be a negative number, but a
really big positive number, and will cause memory overwrite.
This bug can be triggered if either l10n message for function
show_date_relative() in date.c is longer than 30 characters, then
`git blame --date relative` may exit abnormally.
2. When show blame information with relative time, the UTF-8 characters
in time_str will break the alignment of columns after the date field.
This is because the time_buf padding with spaces should have a
constant display width, not a fixed strlen size. So we should call
utf8_strwidth() instead of strlen() for width calibration.

restores it using (eword_t *) math.
In order to do this it's necessary to convert the (uint8_t *)
offset into an (eword_t *) offset. It was doing this by
dividing by the sizeof(size_t). Unfortunately sizeof(size_t)
is not same as sizeof(eword_t) on all platforms.
