Revision 7b3b7e37581fb5266a260687c21af1571b4ade81 authored by Junio C Hamano on 21 December 2010, 18:35:53 UTC, committed by Junio C Hamano on 21 December 2010, 19:16:28 UTC 
am --abort: keep unrelated commits since the last failure and warn
 
After making commits (either by pulling or doing their own work) after a
failed "am", the user will be reminded by next "am" invocation that there
was a failed "am" that the user needs to decide to resolve or to get rid
of the old "am" attempt.  The "am --abort" option was meant to help the
latter.  However, it rewinded the HEAD back to the beginning of the failed
"am" attempt, discarding commits made (perhaps by mistake) since.
