Until now, `git config -h` would have printed help for the old-style
syntax. Now that all modes have proper subcommands though it is
preferable to instead display the subcommand help.
Drop the `NO_INTERNAL_HELP` flag to do so. While at it, drop the help
mismatch in t0450 and add the `--get-colorbool` option to the usage such
that git-config(1)'s synopsis and `git config -h` match.

There's been a lot of incremental effort to make the SYNOPSIS output
in our documentation consistent with the -h output,
e.g. cbe485298b (git reflog [expire|delete]: make -h output
consistent with SYNOPSIS, 2022-03-17) is one recent example, but that
effort has been an uphill battle due to the lack of regression
testing.
This adds such regression testing, we can parse out the SYNOPSIS
output with "sed", and it turns out it's relatively easy to normalize
it and the "-h" output to match on another.
We now ensure that we won't have regressions when it comes to the list
of commands in "expect_help_to_match_txt" below, and in subsequent
commits we'll make more of them consistent.
The naïve parser here gets quite a few things wrong, but it doesn't
need to be perfect, just good enough that we can compare /some/ of
this help output. There's no cases where the output would match except
for the parser's stupidity, it's all cases of e.g. comparing the *.txt
to non-parse_options() output.
Since that output is wildly different than the *.txt anyway let's
leave this for now, we can fix the parser some other time, or it won't
become necessary as we'll e.g. convert more things to using
parse_options().
Having a special-case for "merge-tree"'s 1f0c3a29da (merge-tree:
implement real merges, 2022-06-18) is a bit ugly, but preferred to
blessing that " (deprecated)" pattern for other commands. We'd
probably want to add some other way of marking deprecated commands in
the SYNOPSIS syntax. Syntactically 1f0c3a29da3's way of doing it is
indistinguishable from the command taking an optional literal
"deprecated" string as an argument.
Some of the issues that are left:
* "git show -h", "git whatchanged -h" and "git reflog --oneline -h"
all showing "git log" and "git show" usage output. I.e. the
"builtin_log_usage" in builtin/log.c doesn't take into account what
command we're running.
* Commands which implement subcommands such as like
"multi-pack-index", "notes", "remote" etc. having their subcommands
in a very different order in the *.txt and *.c. Fixing it would
require some verbose diffs, so it's been left alone for now.
* Commands such as "format-patch" have a very long argument list in
the *.txt, but just "[<options>]" in the *.c.
What to do about these has been left out of this series, except to
the extent that preceding commits changed "[<options>]" (or
equivalent) to the list of options in cases where that list of
options was tiny, or we clearly meant to exhaustively list the
options in both *.txt and *.c.
