This patch enables support for Putty.  It has been tested with Putty
0.62 using an Unix created ssh key copied to the private-keys-v1.d
directory on Windows and with a manually crafted sshcontrol file.  It
also works with a smartcard key.

May thanks to gniibe who implemented a proxy in Python to test the
putty/gpg-agent communication.
