Subject: [PATCH] Install git-shell in bindir, again.

/etc/passwd shell field must be something execable, you can't enter
"/usr/bin/git shell" there. git-shell must be present as a separate
executable, or it is useless.

Hi. Recent changes moved away from "git-foo" to "git foo", except for
some commands that needed backwards compatibility. However, git-shell
as a separate binary was removed. I hope you will reinstante git-shell
as a publicly visible binary in bin. Here's why:

The shell field in /etc/passwd is *exec*ed, not interpreted via sh -c
or some such. For example, source of Debian's shadow, containing
/bin/login:

libmisc/shell.c:80:	execle (file, arg, (char *) 0, envp);

I also tested this for real, and having a

test:x:1001:1001:,,,:/home/test:/usr/bin/git-shell

line works, and

test:x:1001:1001:,,,:/home/test:/usr/bin/git shell

just makes ssh loop asking for a password, logging

"User test not allowed because shell /usr/bin/git shell does not exist"

So, as far as I understand, as it currently is, "git shell" is utterly
useless for what it was meant to do. Restoring "git-shell" will fix
it.
