Performance measurements are listed right now as a flat list, which is
fine when we measure big blocks. But when we start adding more and
more measurements, some of them could be just part of a bigger
measurement and a flat list gives a wrong impression that they are
executed at the same level instead of nested.
Add trace_performance_enter() and trace_performance_leave() to allow
indent these nested measurements. For now it does not help much
because the only nested thing is (lazy) name hash initialization
(e.g. called in diff-index from "git status"). This will help more
because I'm going to add some more tracing that's actually nested.

t4150: fix broken test for am --scissors
Tests for "git am --[no-]scissors" [1] work in the following way:
1. Create files with commit messages
2. Use these files to create expected commits
3. Generate eml file with patch from expected commits
4. Create commits using git am with these eml files
5. Compare these commits with expected
The test for "git am --scissors" is supposed to take an e-mail with a
scissors line and in-body "Subject:" header and demonstrate that the
subject line from the e-mail itself is overridden by the in-body header
and that only text below the scissors line is included in the commit
message of the commit created by the invocation of "git am --scissors".
However, the setup of the test incorrectly uses a commit without the
scissors line and without the in-body header in the commit message,
producing eml file not suitable for testing of "git am --scissors".
This can be checked by intentionally breaking is_scissors_line function
in mailinfo.c, for example, by changing string ">8", which is used by
the test. With such change the test should fail, but does not.
Fix broken test by generating eml file with scissors line and in-body
header "Subject:". Since the two tests for --scissors and --no-scissors
options are there to test cutting or keeping the commit message, update
both tests to change the test file in the same way, which allows us to
generate only one eml file to be passed to git am. To clarify the
intention of the test, give files and tags more explicit names.

git pull --rebase=i

pull on branches that do not usually want to be rebased.

add a script to diff rendered documentation
After making a change to the documentation, it's easy to
forget to check the rendered version to make sure it was
formatted as you intended. And simply doing a diff between
the two built versions is less trivial than you might hope:
- diffing the roff or html output isn't particularly
readable; what we really care about is what the end user
will see
- you have to tweak a few build variables to avoid
spurious differences (e.g., version numbers, build
times)
Let's provide a script that builds and installs the manpages
for two commits, renders the results using "man", and diffs
the result. Since this is time-consuming, we'll also do our
best to avoid repeated work, keeping intermediate results
between runs.
Some of this could probably be made a little less ugly if we
built support into Documentation/Makefile. But by relying
only on "make install-man" working, this script should work
for generating a diff between any two versions, whether they
include this script or not.

text in the source code, with an aparent lack of "<" and ">" at both
ends.
It turns out that parse-options machinery takes the whole string and
encloses it inside a pair of "<>", to make it easier for majority
cases that uses a single token placeholder.
The help string was written in a funnily unbalanced way knowing that
the end result would balance out, by somebody who forgot the
presence of PARSE_OPT_LITERAL_ARGHELP, which is the escape hatch
mechanism designed to help such a case. We just should use the
official escape hatch instead.

t6044: add a testcase for index matching head, when head doesn't match HEAD
t6044: verify that merges expected to abort actually abort
index_has_changes(): avoid assuming operating on the_index
read-cache.c: move index_has_changes() from merge.c

Merge branch 'js/rebase-merge-octopus'
"git rebase --rebase-merges" mode now handles octopus merges as
well.
* js/rebase-merge-octopus:
rebase --rebase-merges: adjust man page for octopus support
rebase --rebase-merges: add support for octopus merges
merge: allow reading the merge commit message from a file

Merge branch 'kg/gc-auto-windows-workaround'
"git gc --auto" opens file descriptors for the packfiles before
spawning "git repack/prune", which would upset Windows that does
not want a process to work on a file that is open by another
process. The issue has been worked around.
* kg/gc-auto-windows-workaround:
gc --auto: release pack files before auto packing

Merge branch 'jm/cache-entry-from-mem-pool'
For a large tree, the index needs to hold many cache entries
allocated on heap. These cache entries are now allocated out of a
dedicated memory pool to amortize malloc(3) overhead.
* jm/cache-entry-from-mem-pool:
block alloc: add validations around cache_entry lifecyle
block alloc: allocate cache entries from mem_pool
mem-pool: fill out functionality
mem-pool: add life cycle management functions
mem-pool: only search head block for available space
block alloc: add lifecycle APIs for cache_entry structs
read-cache: teach make_cache_entry to take object_id
read-cache: teach refresh_cache_entry to take istate

Merge branch 'jt/fetch-nego-tip'
"git fetch" learned a new option "--negotiation-tip" to limit the
set of commits it tells the other end as "have", to reduce wasted
bandwidth and cycles, which would be helpful when the receiving
repository has a lot of refs that have little to do with the
history at the remote it is fetching from.
* jt/fetch-nego-tip:
fetch-pack: support negotiation tip whitelist

Merge branch 'jt/fetch-pack-negotiator'
Code restructuring and a small fix to transport protocol v2 during
fetching.
* jt/fetch-pack-negotiator:
fetch-pack: introduce negotiator API
fetch-pack: move common check and marking together
fetch-pack: make negotiation-related vars local
fetch-pack: use ref adv. to prune "have" sent
fetch-pack: directly end negotiation if ACK ready
fetch-pack: clear marks before re-marking
fetch-pack: split up everything_local()
