defer "can't load gundo" warning
Only inform that gundo didn't load when an attempt is made to invoke it.
Too many hosts still don't have vim 7.3, but I'd like to do a straight
update of my vimfiles from my dvcs without needing any fiddly
conditionals in order to load vim without a warning message.
