combine-diff.c: teach combined diffs about line prefix
When running "git log --graph --cc -p" the diff output for merges is not indented by the graph structure, unlike the diffs of non-merge commits (added in commit 7be5761 - diff.c: Output the text graph padding before each diff line). Fix this by teaching the combined diff code to output diff_line_prefix() before each line. Signed-off-by: John Keeping <john@keeping.me.uk> Signed-off-by: Junio C Hamano <gitster@pobox.com>
