connect.c: Support PuTTY plink and TortoisePlink as SSH on Windows
OpenSSH uses -p to specify custom ports, while PuTTY plink and TortoisePlink use -P. Git now detects if plink is in GIT_SSH and modify its flags as necessary. We call plink with -batch, so that it will error out with an error message instead of waiting for user input. As reported in msysGit issue 96, plink wants to interact with the user asking if a host key should be accepted, but this just blocks the terminal, since plink tries to get the answer from stdin. However, stdin is already connected to Git that wants to send input to the remote command. But we do not pass -batch to TortoisePlink, because TortoisePlink uses a GUI to communicate with the user, and it does not understand -batch. Signed-off-by: Edward Z.
