Since we want to get rid of git-bisect.sh, it would be necessary to convert bisect.c exit() calls to return statements so that errors can be reported. Let's prepare for that by making it possible to return different error codes than just 0 or 1.

Different error codes might enable a bisecting script calling the bisect command that uses this function to do different things depending on the exit status of the bisect command.
