[PATCH] git-mergetool--lib.sh: make check_unchanged return 1 on invalid read

From: Jay Soffian <jaysoffian@gmail.com>

Message-ID: <1316462592-27255-1-git-send-email-jaysoffian@gmail.com>

Else when the user hits ctrl-c at the "Was the merge successful? [y/n]" prompt, mergetool goes into an infinite loop asking for input.
