It's been quite a long time since the earlier discussion, but I wonder why
you need the colon before "foo" for this new shorthand.  I *think* you are
also introducing "--format=short" as a synonym to "--pretty=short", but
I do not think it is necessary.

Maybe somebody wants to document it.

Needs trivial tests.

	struct strbuf fmt = STRBUF_INIT;
        revs->verbose_header = 1;
        strbuf_addf(&fmt, "tformat:%s", arg + 9);
        get_commit_format(fmt.buf, revs);
        strbuf_release(&fmt);
