Re: [PATCH 04/10] Migrate git-clone to use git-rev-parse --parseopt

[Junio C Hamano <gitster@pobox.com>]

Gaah.

I'd blame Linus for suggesting to make parseopt part of
rev-parse, the latter of which makes sense only inside git while
the former of which makes sense outside git.

Would something like this help?
