When checking out a branch that is set to build on top of another
branch (often, a remote-tracking branch), "git checkout" reports how
your work relates to the other branch, e.g.
Your branch is behind 'origin/master', and can be fast-forwarded.
Back when this feature was introduced, this was only done for
branches that build on remote-tracking branches, but 5e6e2b48 (Make
local branches behave like remote branches when --tracked,
2009-04-01) added support to give the same report for branches that
build on other local branches (i.e. branches whose branch.*.remote
variables are set to '.'). Unlike the support for the branches
building on remote-tracking branches, however, this did not take
into account the fact that branch.*.merge configuration is allowed
to record a shortened branch name.
When branch.*.merge is set to 'master' (not 'refs/heads/master'),
i.e. "my branch builds on the local 'master' branch", this caused
"git checkout" to report:
Your branch is based on 'master', but the upstream is gone.
The upstream is our repository and is definitely not gone, so this
output is nonsense.
The fix is fairly obvious; just like the branch name is DWIMed when
"git pull" merges from the 'master' branch without complaint on such
a branch, the name of the branch the current branch builds upon
needs to be DWIMed the same way.

It is possible that a user is trying to run a git command and fail
to realize that they are not in a git repository or working tree.
When trying to complete an operation, __git_refs would fall to a
degenerate case and attempt to use "git for-each-ref", which would
emit the error.
Hide this error message coming from "git for-each-ref".

Originally the color-parsing function was used only for
config variables. It made sense to pass the variable name so
that the die() message could be something like:
$ git -c color.branch.plain=bogus branch
fatal: bad color value 'bogus' for variable 'color.branch.plain'
These days we call it in other contexts, and the resulting
error messages are a little confusing:
$ git log --pretty='%C(bogus)'
fatal: bad color value 'bogus' for variable '--pretty format'
$ git config --get-color foo.bar bogus
fatal: bad color value 'bogus' for variable 'command line'
This patch teaches color_parse to complain only about the
value, and then return an error code. Config callers can
then propagate that up to the config parser, which mentions
the variable name. Other callers can provide a custom
message. After this patch these three cases now look like:
$ git -c color.branch.plain=bogus branch
error: invalid color value: bogus
fatal: unable to parse 'color.branch.plain' from command-line config
$ git log --pretty='%C(bogus)'
error: invalid color value: bogus
fatal: unable to parse --pretty format
$ git config --get-color foo.bar bogus
error: invalid color value: bogus
fatal: unable to parse default color value

Many config-parsing helpers, like parse_branch_color_slot,
take the name of a config variable and an offset to the
"slot" name (e.g., "color.branch.plain" is passed along with
"13" to effectively pass "plain"). This is leftover from the
time that these functions would die() on error, and would
want the full variable name for error reporting.
These days they do not use the full variable name at all.
Passing a single pointer to the slot name is more natural,
and lets us more easily adjust the callers to use skip_prefix
to avoid manually writing offset numbers.
This is effectively a continuation of 9e1a5eb, which did the
same for parse_diff_color_slot. This patch covers all of the
remaining similar constructs.

Usually running a test under "-v" makes it clear which
command is failing. However, sometimes it can be useful to
also see a complete trace of the shell commands being run in
the test. You can do so without any support from the test
suite by running "sh -x tXXXX-foo.sh". However, this
produces quite a large bit of output, as we see a trace of
the entire test suite.
This patch instead introduces a "-x" option to the test
scripts (i.e., "./tXXXX-foo.sh -x"). When enabled, this
turns on "set -x" only for the tests themselves. This can
still be a bit verbose, but should keep things to a more
manageable level. You can even use "--verbose-only" to see
the trace only for a specific test.
The implementation is a little invasive. We turn on the "set
-x" inside the "eval" of the test code. This lets the eval
itself avoid being reported in the trace (which would be
long, and redundant with the verbose listing we already
showed). And then after the eval runs, we do some trickery
with stderr to avoid showing the "set +x" to the user.
We also show traces for test_cleanup functions (since they
can impact the test outcome, too). However, we do avoid
running the noop ":" cleanup (the default if the test does
not use test_cleanup at all), as it creates unnecessary
noise in the "set -x" output.

We have had "git -C $there" to first go to a different directory
and run a Git command without changing the arguments for quite some
time. Use it instead of (cd $there && git ...) in the completion
script.
This allows us to lose the work-around for misfeatures of modern
interactive-minded shells that make "cd" unusable in scripts (e.g.
end users' $CDPATH taking us to unexpected places in any POSIX
shell, and chpwd functions spewing unwanted output in zsh).
Based on Øystein Walle's idea, which was raised during the
discussion on the solution by Brandon Turner for a problem zsh users
had with RVM which mucks with chpwd_functions in users' environments
(https://github.com/wayneeseguin/rvm/issues/3076).
As $root variable, which is used to direct where to chdir to, is set
to "." based on if $2 to __git_index_files is set (not if it is empty),
the only caller of the function is fixed not to pass the optional $2
when it does not want us to switch to a different directory. Otherwise
we would end up doing "git -C '' command...", which would not work.
Maybe we would want "git -C '' command..." to mean "do not chdir
anywhere", but that is a spearate topic.
