Make sure GPG-agent does not mess up the tty

[sheeviZi]

When gpg-agent is used as an ssh-agent and configured with pinentry-ncurses, it messes up the terminal immediately after you cd into a git repository with an ssh remote.

Fixes issue #366.

I can help you reproduce it if you ask.

@sheeviZi that looks very simple, but what is the intended effect of this change?

~After applying this patch, I don't have the problem of the mangled input anymore (hurray! 🏆), but I also don't see any pinentry prompt. This is perfectly fine with me, I'm just trying to understand what's going on under the hood.~

Sorry I spoke too fast. Looks like my gpg-agent wasn't set up properly while I was trying to reproduce. See review comment.
