From ad230267f8ecae6cb4f0da17d7a5f75ba38203e2 Mon Sep 17 00:00:00 2001 From: Johan Herland Date: Mon, 15 Nov 2010 18:39:52 +0100 Subject: ui-log: Line-wrap long commit subjects when showmsg is enabled When showmsg is disabled ui-log truncates long commit subjects. This is good. However, the same is not desirable when showmsg is enabled, since you then end up with a truncated commit subject followed by the rest of the commit message below. Instead, when showmsg is enabled (and we're using all this space to display the entire commit message, anyway), line-wrap the commit subject instead of truncating it.
