Revision ec245ba04944473ba6657a826643ef90ed02b51d authored by David Aguilar on 20 January 2012, 07:47:35 UTC, committed by Junio C Hamano on 23 January 2012, 19:50:22 UTC
Some merge tools cannot cope when $LOCAL, $BASE, or $REMOTE are missing. $BASE can be missing when two branches independently add the same filename. Provide an empty file to make these tools happy. When a delete/modify conflict occurs, $LOCAL and $REMOTE can also be missing. We have special case code to handle such case so this change may not affect that codepath, but try to be consistent and create an empty file for them anyway.
