From d694a17986a28bbc19e2a6c32404ca24572e400f Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Thu, 14 Apr 2016 15:35:09 -0700 Subject: [PATCH] ll-merge: use a longer conflict marker for internal merge The primary use of conflict markers is to help the user who resolves the final (outer) merge by hand to show which part came from which branch by separating the blocks of lines apart. When the conflicted parts from a "virtual ancestor" merge created by merge-recursive remains in the common ancestor part in the final result, however, the conflict markers that are the same size as the final merge become harder to see. Increase the conflict marker size slightly for these inner merges so that the markers from the final merge and cruft from internal merge can be distinguished more easily. This would help reduce the common issue that prevents "rerere" from being used on a really complex conflict.
