The merge-one-file tool predates the invention of
GIT_WORK_TREE. By the time GIT_WORK_TREE was invented, most
people were using the merge-recursive strategy, which
handles resolving internally. Therefore these features have
had very little testing together.
For the most part, merge-one-file just works with
GIT_WORK_TREE; most of its heavy lifting is done by plumbing
commands which do respect GIT_WORK_TREE properly. The one
exception is a shell redirection which touches the worktree
directly, writing results to the wrong place in the presence
of a GIT_WORK_TREE variable.
This means that merges won't even fail; they will silently
produce incorrect results, throwing out the entire "theirs"
side of files which need content-level merging!
This patch makes merge-one-file chdir to the toplevel of the
working tree (and exit if we don't have one). This most
closely matches the assumption made by the original script
(before separate work trees were invented), and matches what
happens when the script is called as part of a merge
strategy.
While we're at it, we'll also error-check the call to cat.
Merging a file in a subdirectory could in fact fail, as the
redirection relies on the "checkout-index" call just prior
to create leading directories. But we never noticed, since
we ignored the error return from running cat.

There were no tests for either, except a brief use in
t1200-tutorial.
These tools are not used much these days, as most people
use the merge-recursive strategy, which handles everything
internally. However, they are used by the "octopus" and
"resolve" strategies, as well as any custom strategies
or merge scripts people have built around them.
For example, together with read-tree, they are the simplest
way to do a basic content-level merge without checking out
the entire repository contents beforehand.
This script adds a basic test of the tools to perform one
content-level merge. It also shows a failure of the tools to
work properly in the face of GIT_WORK_TREE or core.worktree.

Here is a 'feature' command for streams to use to require support for
the notemodify (N) command.
When the 'feature' facility was introduced (v1.7.0-rc0~95^2~4,
2009-12-04), the notes import feature was old news (v1.6.6-rc0~21^2~8,
2009-10-09) and it was not obvious it deserved to be a named feature.
But now that is clear, since all major non-git fast-import backends
lack support for it.
Details: on git version with this patch applied, any "feature notes"
command in the features/options section at the beginning of a stream
will be treated as a no-op. On fast-import implementations without
the feature (and older git versions), the command instead errors out
with a message like
This version of fast-import does not support feature notes.
So by declaring use of notes at the beginning of a stream, frontends
can avoid wasting time and other resources when the backend does not
support notes. (This would be especially important for backends that
do not support rewinding history after a botched import.)

The "feature" command allows streams to specify options for the import
that must not be ignored. Logically, they are part of the stream,
even though technically most supported features are synonyms to
command-line options.
Make this more obvious by being more explicit about how the analogy
between most "feature" commands and command-line options works. Treat
the feature (import-marks) that does not fit this analogy separately.

The "[add] ignore-errors" tweakable introduced by v1.5.6-rc0~30^2 (Add
a config option to ignore errors for git-add, 2008-05-12) does not
follow the usual convention for naming values in the git configuration
file.
What convention? Glad you asked.
The section name indicates the affected subsystem.
The subsection name, if any, indicates which of
an unbound set of things to set the value for.
The variable name describes the effect of tweaking
this knob.
The section and variable names can be broken into
words using bumpyCaps in documentation as a hint to
the reader. These word breaks are not significant
at the level of code, since the section and variable
names are not case sensitive.
The name "add.ignore-errors" includes a dash, meaning a naive
configuration file like
[add]
ignoreErrors
does not have any effect. Avoid such confusion by renaming to the
more consistent add.ignoreErrors, but keep the old version for
backwards compatibility.

The description for core.autocrlf refers to reads from / writes to
"the filesystem", the only use of this rather ambiguous term, which
technically could be referring to the git object database. (All other
mentions are part of phrases such as "..filesystems (like NFS)..").
Other sections, including the section on core.safecrlf, use the term
"work tree" for the same purpose as the term "the filesystem" is used in
the core.autocrlf section, so that seems like a good alternative, which
makes it clearer what direction the addition/removal of CR characters
occurs in.

The diffstat "added" and "changed" fields generally store
line counts; however, for binary files, they store file
sizes. Since we store and print these values as ints, a
diffstat on a file larger than 2G can show a negative size.
Instead, let's use uintmax_t, which should be at least 64

Consider an evil merge of two commits A and B, both of which have a
file 'foo', but the merge result does not have that file.
The combined-diff code learned in 4462731 (combine-diff: do not punt
on removed or added files., 2006-02-06) to concisely show only the
removal, since that is the evil part and the previous contents are
presumably uninteresting.
However, to diagnose an empty merge result, it overloaded the variable
that holds the file's length. This means that the check also triggers
for truncated files. Consequently, such files were not shown in the
diff at all despite the merge being clearly evil.
Fix this by adding a new variable that distinguishes whether the file
was deleted (which is the case 4462731 handled) or truncated. In the
truncated case, we show the full combined diff again, which is rather
spammy but at least does not hide the evilness.

v1.7.0-rc0~18^2 (branch -d: base the "already-merged" safety on the
branch it merges with, 2009-12-29) taught ‘git branch’ a new heuristic
for when it is safe to delete a branch without forcing the issue. It
is safe to delete a branch "topic" without second thought if:
- the branch "topic" is set up to pull from a (remote-tracking,
usually) branch and is fully merged in that "upstream" branch, or
- there is no branch.topic.merge configuration and branch "topic" is
fully merged in the current HEAD.
Update the man page to acknowledge the new rules.
