[PATCH] COMMIT_MSG - cygport patches

[Brian Inglis]

Sorry,
These cygport patches were expected to allow edits as usual but just went!
Minor "unrelated" ~/.gitconfig changes seem to have removed confirmation.

This should have been an -F COMMIT_MSG but I typed -m COMMIT_MSG.

The next fixes a cygport announce SMTP server issue using code from git send-email.

The last fixes a cygport install infinite loop when there is a symlink along the
path to DEST host prefix.
