This also makes the code somewhat cleaner as it follows the pattern

<include statements>

by specifying which flags to activate in the first part, and actually
activating them in the last one.

The one-shot environment variable syntax:
FOO=BAR some-program
is unportable when some-program is actually a shell
function, like test_must_fail (on some shells FOO remains
set after the function returns, and on others it does not).
We sometimes get around this by using env, like:
test_must_fail env FOO=BAR some-program
But that only works because test_must_fail's arguments are
themselves a command which can be run. You can't run:
env FOO=BAR test_must_fail some-program
because env does not know about our shell functions. So
there is no equivalent for test_commit, for example, and one
must resort to:
(
FOO=BAR
export FOO
test_commit
)
which is a bit verbose. Let's add a version of "env" that
works _inside_ the shell, by creating a subshell, exporting
variables from its argument list, and running the command.
Its use is demonstrated on a currently-unportable case in
t4014.

Running tests with '-x' option to trace the individual command
executions is a useful way to debug test scripts, but some tests
that capture the standard error stream and check what the command
said can be broken with the trace output mixed in. When running
our tests under "bash", however, we can redirect the trace output
to another file descriptor to keep the standard error of programs
being tested intact.

"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."
* js/name-rev-use-oldest-ref:
name-rev: include taggerdate in considering the best name
Interactive rebase uses 'git cherry-pick' and 'git merge' to replay
commits. Both invoke the 'rerere' machinery when they fail due to merge
conflicts. Note that all code paths with these two commands also invoke
the shell function die_with_patch when the commands fail.
Since commit 629716d2 ("rerere: do use multiple variants") the second
operation of the rerere machinery can be observed by a duplicated
message "Recorded preimage for 'file'". This second operation records
the same preimage as the first one and, hence, only wastes cycles.
Remove the 'git rerere' invocation from die_with_patch.
Shell function die_with_patch can be called after the failure of
"git commit", too, which also calls into the rerere machinery, but it
does so only after a successful commit to record the resolution.
Therefore, it is wrong to call 'git rerere' from die_with_patch after
"git commit" fails.

The function trim_common_tail() exits early if context lines are

context lines that might belong to a changed function. As a result

If a new function and a preceding empty line is appended, diff -W shows
the previous function in full in order to provide context for that empty
line. In most languages empty lines between sections are not
interesting in and off themselves and showing a whole extra function for
them is not what we want.
Skip empty lines when checking of the appended chunk starts with a
function line, thereby avoiding to extend the context just for them.

If lines are added at the end of a file, diff -W shows the whole file.
That's because get_func_line() only considers the pre-image and gives up
if it sees a record index beyond its end.
Consider the post-image as well to see if the added lines already make
up a full function. If it doesn't then search for the previous function
line by starting from the bottom of the pre-image, thereby avoiding to
confuse get_func_line().
Reuse the existing label called "again", as it's exactly where we need
to jump to when we're done handling the pre-context, but rename it to
"post_context_calculation" in order to document its new purpose better.

Backticks are emphasized through monospaced styling in the HTML
version of Git documentation. But they were left unstyled in the
manual pages.
To make the man pages more comfortably read, `MAN_BOLD_LITERAL` was
added by 5121a6d (Documentation: option to render literal text as
bold for manpages, 2009-03-27). It allowed the user to build the
manpages with literals in bold style.
For precaution it was not set by default back then.
Since 79c461d (docs: default to more modern toolset, 2010-11-19), it
is assumed ASCIIDOC 8 and at least docbook-xsl 1.73 are used, so the
need for compatibility concern is much lessor now.
Remove `MAN_BOLD_LITERAL`, and typeset literals as bold by default .

The DEVELOPER knob was introduced in 658df95 (add DEVELOPER makefile
knob to check for acknowledged warnings, 2016-02-25), and works well
when used as "make DEVELOPER=1", and when the configure script was not
used.
However, the advice given in CodingGuidelines to add DEVELOPER=1 to
config.mak does not: config.mak is included after testing for
DEVELOPER in the Makefile, and at least GNU Make's manual specifies
"Conditional directives are parsed immediately", hence the config.mak
declaration is not visible at the time the conditional is evaluated.
Also, when using the configure script to generate a
config.mak.autogen, the later file contained a "CFLAGS = <flags>"
initialization, which overrode the "CFLAGS += -W..." triggered by
DEVELOPER.

When loosening a pack, the current pack_id gets reused when
checkpointing and the import does not terminate. This causes
problems after checkpointing as the object table, branch, and
tag lists still contains pre-checkpoint references to the
recycled pack_id.
Merely clearing the object_table as suggested by Jeff King in
http://mid.gmane.org/20160517121330.GA7346@sigill.intra.peff.net

to object entries.

errors, but can lead to misleading crash reports and core dumps,

git-log(1) documents that when specifying the `%C(auto)` format
placeholder will "turn on auto coloring on the next %placeholders
until the color is switched again."
However, when `%C(auto)` is used, the present implementation will turn
colors on unconditionally (even if the color configuration is turned off
for the current context - for example, `--no-color` was specified or the
color is `auto` and the output is not a tty).
Update `format_commit_one` to examine the current context when a format
string of `%C(auto)` is specified, which ensures that we will not
unconditionally write colors. This brings that behavior in line with
the behavior of `%C(auto,<colorname>)`, and allows the user the ability
to specify that color should be displayed only when the output is a
tty.
Additionally, add a test for `%C(auto)` and update the existing tests
for `%C(auto,...)` as they were misidentified as being applicable to
`%C(auto)`.
