[GUILT 0/2] Teach "guilt graph" to ignore some files.

If you use a ChangeLog, all output from "guilt graph" will be a boring line of commits. By using "guilt graph -x ChangeLog" things will look more interesting.

Also: simplify getfiles.

(This work is also available on the guilt-graph-ignore-2015-v1 branch of the git://repo.or.cz/guilt/ceder.git repository. (That branch is based on the doc-dash-2015-v1 branch that contains my documentation fixes, so if you just want these two commits you will have to cherry-pick.))

  Teach "guilt graph" the "-x exclude-pattern" option.
