From ca9b37e5a8a76b7b5c9990481ce4f9894dd40392 Mon Sep 17 00:00:00 2001 From: Stefan Beller Date: Wed, 7 Sep 2016 16:36:48 -0700 Subject: [PATCH] diff: remove dead code When `len < 1`, len has to be 0 or negative, emit_line will then remove the first character and by then `len` would be negative. As this doesn't happen, it is safe to assume it is dead code. This continues to simplify the code, which was started in b8d9c1a66b (2009-09-03, diff.c: the builtin_diff() deals with only two-file comparison).
