Change do-not-merge pattern to "do not merge"

This should avoid the problem we recently had with
automatically-generated merge messages, while still letting people
specify commits not to merge.
* admin/gitmerge.el (gitmerge-skip-regexp): Add "do not merge".
(gitmerge-highlight-skip-regexp): Fold case when searching
for gitmerge-skip-regexp.
