After handling options, any leftover arguments should be
commands. However, we pass through "--help" and "--version",
so that we convert them into "git help" and "git version"
respectively.
This is a straightforward use of skip_prefix to avoid a
magic number, but while we are there, it is worth adding a
comment to explain this otherwise confusing behavior.

Another option would be to teach handle_options to convert "--version"
into "version" itself. That's more disruptive, but I think would be
less confusing.
