Makes sense.

Not about this patch: is there a way to detect this automatically?
E.g. if a command in git.c::commands doesn't appear in
command-list.txt, could we make Git fail "make test"?

optional: This might be an unfamiliar term to people not thinking of the
plumbing fixture / chrome analogy.  Is there anything we should do to
help them understand what's going on?

E.g. "git help glossary" says

	Porcelains expose more of a SCM interface than the plumbing.

tabs snuck in.
