It can be useful in the test suite to be able to iterate
over the list of builtins. We could do this with some
Makefile magic. But since the authoritative list is in the
commands array inside git.c, and since this could also be
handy for debugging, let's add a hidden command-line option
to dump that list.

The forward declaration here is necessary because of the function
ordering. We could push handle_options() much lower in the file, but I
didn't think it was worth the churn.
