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.
Signed-off-by: Jeff King <peff@peff.net> --- 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.
