Thomas Arendsen Hein <thomas@intevation.de> [Thu, 16 Jun 2011 22:47:34 +0200] rev 14650
revset: add desc(string) to search in commit messages
Like keyword(), but does not search in filenames and users.
No grepdesc() or descgrep() added, because it might be bad to introduce
grepfoo() versions of too many string searches.
