From 747b035dda97ae359ed00d84744acfa8cc009fb2 Mon Sep 17 00:00:00 2001 From: Lukas Fleischer Date: Wed, 14 Aug 2013 10:50:31 +0200 Subject: Extract filepair_cb from ui-patch.c Move filepair_cb() from ui-patch.c to ui-shared.c and rename it to filepair_cb_raw(). This callback will be used in ui-diff.c in a follow-up patch. Note that it is not straightforward to extract filepair_cb() from ui-diff.c which is why it is not done here as well.
