Subject: git-blame.el: use mapc instead of mapcar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Using mapcar here is a waste of memory because the mapped result
is not used.

Noticed by emacs ("Warning: `mapcar' called for effect").

[jn: split from a larger patch, with new description]
