Quite possibly, yes.

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).

Also "git gitk gitweb" may want to be made into a Makefile variable
to be shared in the "above" and "below" (I do not know what to call
them offhand---they are programs with special build rules that are
not covered by ALL/SCRIPT_LIB/BUILTIN).

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.

By the way, do we have a documentation for git-gui?  Perhaps it may
want to be added to that "git gitk gitweb" list as a reminder that
it lacks documentation.  One of the goals of the person who runs
"make check-docs" should be to reduce the special case that appears
at the beginning of that case statement.

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

I also wonder why "help" is not treated as a built-in?  Perhaps we
should throw it in to "git gitk gitweb" list?  After all, it is a
command that is available in "git foo" form, is documented, and is
listed in the command-list.txt file.

One issue I notice a few weeks ago is that `git help --all` does not list all of the available git help pages, rather it just limits itself to the available command pages.

This means that new users can't discover those additional help pages in any easy manner.

I had an initial look at what might be involved in adding a --guides option, shifting the current --all to --cmd (or --command) and then make --all list both commands and guides.

The need for help to list all the guides is parallel to these patches. I didn't get that far in working out how to approach such a patch which would discovere the available guides - I'm on GfW-msysgit which normally uses web display.

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
