Actually, my "already handled specially" is not quite accurate. That
special list is "things that are commands but are not necessarily
mentioned in the Makefile variables". But this list is "things that are
documented but do not begin with git-". The two should mostly be the
same, but the whole point of this exercise is to make sure they _are_
the same.

A better solution is to simply ask the Documentation directory what the
commands are, since it already knows (in the form of MAN1_TXT).

I couldn't think of a special name, either, but I think it is sufficient
to just create a new ALL_COMMANDS variable that includes those other
things, and then add to it.

Yes, it should be checked (and git-citool, too).

Historically it was part of git.c, but these days it is a built-in and
does not need any special treatment from check-docs.

Patches for all to follow (on top of my previous 4).

  [5/4]: check-docs: factor out command-list
  [6/4]: check-docs: list git-gui as a command
  [7/4]: check-docs: drop git-help special-case
  [8/4]: check-docs: get documented command list from Makefile
