Re: [PATCH] Allow git-shell to be used as a ssh forced-command

However, the patch in its current form will definitely break gitosis if
it doesn't unset SSH_ORIGINAL_COMMAND.

... and any home-made script without knowledge of this feature. If I
wanted to add some restrictions to git-shell, it would seem natural to
me to write a script like

#! /bin/sh

if [ ??? ]; then
	git-shell $whatever
else
	echo "Sorry, forbidden"
	exit 1
fi

(I never did this with Git because I never had to manage any kind of
permission control with it, but I have a script like that for SVN that
adds some argument to the SVN command)

If the command ignores its arguments, and use some other environment
variable instead, then the security hole is not far.
