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.

Implement the logic to process trailers from the input message
and from arguments.
At the beginning trailers from the input message are in their
own "in_tok" doubly linked list, and trailers from arguments
are in their own "arg_tok" doubly linked list.
The lists are traversed and when an "arg_tok" should be "applied",
it is removed from its list and inserted into the "in_tok" list.

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.

Neither the AsciiDoc nor the Asciidoctor documentation specify whether
the same number of delimiter characters must be used to end a block as
to begin it, although both sets of documentation show exactly matching
pairs. AsciiDoc allows mismatches, but AsciiDoctor apparently does not.
Adjust the pretty formats documentation to use matching pairs to prevent
a misrendering where the remainder of the document was rendered as a
listing block.
