3444ec2e ("fsmonitor: don't fill bitmap with entries to be removed",
2019-10-11) added a handful of sanity checks that make sure that a
bit position in fsmonitor bitmap does not go beyond the end of the
index. As each bit in the bitmap corresponds to a path in the
index, this is the right check most of the time.
Except for the case when we are in the split-index mode and looking
at a delta index that is to be overlayed on the base index but
before the base index has actually been merged in, namely in read_
and write_fsmonitor_extension(). In these codepaths, the entries in
the split/delta index is typically a small subset of the entire set
of paths (otherwise why would we be using split-index?), so the
bitmap used by the fsmonitor is almost always larger than the number
of entries in the partial index, and the incorrect comparison would
trigger the BUG().

The comments for the staging/unstaging test did not accurately
describe the scenario being tested. It is not essential that
the test files being staged/unstaged appear at the end of the
index. All that is required is that the test files are not
flagged with CE_FSMONITOR_VALID and have a position in the
index greater than the number of entries in the index after
unstaging.
The comment for this test has been updated to be more
accurate with respect to the scenario that's being tested.

While doing some testing with fsmonitor enabled I found
that git commands would segfault after staging and
unstaging an untracked file. Looking at the crash it
appeared that fsmonitor_ewah_callback was attempting to
adjust bits beyond the bounds of the index cache.
Digging into how this could happen it became clear that
the fsmonitor extension must have been written with
more bits than there were entries in the index. The
root cause ended up being that fill_fsmonitor_bitmap was
populating fsmonitor_dirty with bits for all entries in
the index, even those that had been marked for removal.
To solve this problem fill_fsmonitor_bitmap has been
updated to skip entries with the the CE_REMOVE flag set.
With this change the bits written for the fsmonitor
extension will be consistent with the index entries
written by do_write_index. Additionally, BUG checks
have been added to detect if the number of bits in
fsmonitor_dirty should ever exceed the number of
entries in the index again.
Another option that was considered was moving the call
to fill_fsmonitor_bitmap closer to where the index is
written (and where the fsmonitor extension itself is
written). However, that did not work as the
fsmonitor_dirty bitmap must be filled before the index
is split during writing.

Inspired by 21416f0a07 ("restore: fix typo in docs", 2019-08-03), I ran
"git grep -E '(\b[a-zA-Z]+) \1\b' -- Documentation/" to find other cases
where words were duplicated, e.g. "the the", and in most cases removed
one of the repeated words.
There were many false positives by this grep command, including
deliberate repeated words like "really really" or valid uses of "that
that" which I left alone, of course.
I also did not correct any of the legitimate, accidentally repeated
words in old RelNotes.

Commit 01d3a526ad (t0000: check whether the shell supports the "local"
keyword, 2017-10-26) added a test to gather data on whether people run
the test suite with shells that don't support "local".
After almost two years, nobody has complained, and several other uses
have cropped up in test-lib-functions.sh. Let's declare it acceptable to
use.

t1410.3 ("corrupt and checks") fails when run using dash versions
before 0.5.8, with a cryptic message:
mv: cannot stat '.git/objects//e84adb2704cbd49549e52169b4043871e13432': No such file or directory
The function generating that path:
test_oid_to_path () {
echo "${1%${1#??}}/${1#??}"
}
which is supposed to produce a result like
12/3456789....
But a dash bug[*] causes it to instead expand to
/3456789...
The stream of symbols that makes up this function is hard for humans
to follow, too. The complexity mostly comes from the repeated use of
the expression ${1#??} for the basename of the loose object. Use a
variable instead --- nowadays, the dialect of shell used by Git
permits local variables, so this is cheap.
An alternative way to work around [*] is to remove the double-quotes
around test_oid_to_path's return value. That makes the expression
easier for dash to read, but harder for humans. Let's prefer the
rephrasing that's helpful for humans, too.
Noticed by building on Ubuntu trusty, which uses dash 0.5.7.
[*] Fixed by v0.5.8~13 ("[EXPAND] Propagate EXP_QPAT in subevalvar, 2013-08-23).

Ever since commit 8c8e5bd6eb33 ("merge-recursive: switch directory
rename detection default", 2019-04-05), the default handling with
directory rename detection was to report a conflict and leave unstaged
entries in the index. However, when creating a virtual merge base in
the recursive case, we absolutely need a tree, and the only way a tree
can be written is if we have no unstaged entries -- otherwise we hit a
BUG().
There are a few fixes possible here which at least fix the BUG(), but
none of them seem optimal for other reasons; see the comments with the
new testcase 13e in t6043 for details (which testcase triggered a BUG()
prior to this patch). As such, just opt for a very conservative and
simple choice that is still relatively reasonable: have the recursive
case treat 'conflict' as 'false' for opt->detect_directory_renames.

In 1771be90 "commit-graph: merge commit-graph chains" (2019-06-18),
the method sort_and_scan_merged_commits() was added to merge the
commit lists of two commit-graph files in the incremental format.
Unfortunately, there was an off-by-one error in that method around
incrementing num_extra_edges, which leads to an incorrect offset
for the base graph chunk.
When we store an octopus merge in the commit-graph file, we store
the first parent in the normal place, but use the second parent
position to point into the "extra edges" chunk where the remaining
parents exist. This means we should be adding "num_parents - 1"
edges to this list, not "num_parents - 2". That is the basic error.
The reason this was not caught in the test suite is more subtle.
In 5324-split-commit-graph.sh, we test creating an octopus merge
and adding it to the tip of a commit-graph chain, then verify the
result. This _should_ have caught the problem, except that when
we load the commit-graph files we were overly careful to not fail
when the commit-graph chain does not match. This care was on
purpose to avoid race conditions as one process reads the chain
and another process modifies it. In such a case, the reading
process outputs the following message to stderr:
warning: commit-graph chain does not match
These warnings are output in the test suite, but ignored. By
checking the stderr of `git commit-graph verify` to include
the expected progress output, it will now catch this error.

"Can not" suggests one has the option to not do something, whereas
"cannot" more strongly suggests something is disallowed or impossible.
Noticed "can not", mistakenly used instead of "cannot" in git help
glossary, then ran git grep 'can not' and found many other instances.
Only files in the Documentation folder were modified.
'Can not' also occurs in some source code comments and some test
assertion messages, and there is an error message and translation "can
not move directory into itself" which I may fix and submit separately
from the documentation change.
Also noticed and fixed "is does" in git help fetch, but there are no
other occurrences of that typo according to git grep.
