I don't think this should ever been exposed in the user interface. It
may be interesting to add this in the API (an extra argument letting
the caller decide whether to fail early or not), but the user running
"git pull" normally expects it to succeed, and can clearly accept that
a failure takes as much time as a success, especially when the better
error message lets him save a few tens of seconds, if not minutes.
