 Random changes to parse-options implementation.

 Will merge to 'next'?

As I already said, I am not convinced by the "exhaustive case"
thing.  Other than that, I think this is OK.

* ab/align-parse-options-help (2021-09-22) 4 commits
 - parse-options: properly align continued usage output
 - git rev-parse --parseopt tests: add more usagestr tests
 - send-pack: properly use parse_options() API for usage string
 - parse-options API users: align usage output in C-strings

 When "git cmd -h" shows more than one line of usage text (e.g.
 the cmd subcommand may take sub-sub-command), parse-options API
 learned to align these lines, even across i18n/l10n.

This was more or less "Meh" for me.

 - help: move column config discovery to help.c library
 - help / completion: make "git help" do the hard work
 - help tests: test --config-for-completion option & output
 - help: simplify by moving to OPT_CMDMODE()

 Teach "git help -c" into helping the command line completion of
 configuration variables.

This is probably a good thing to do.  I do not remember what
implementation nits were still there offhand.
