Charles Bailey af3147147f mergetool: Remove explicit references to /dev/tty ...

mergetool used /dev/tty to switch back to receiving input from the user
via inside a block with a redirected stdin.

This harms testability, so change mergetool to save its original stdin
to an alternative fd in this block and restore it for those sub-commands
that need the original stdin.

Includes additional compatibility fix from Jonathan Nieder.
