Does the problem still exist in the latest Emacs versions?  E.g., in
Emacs 23.3, "M-x auto-tail TAB" completes to auto-revert-tail-mode
without anything special you'd need to do.  The secret is that
completion was lately extended, and is now much smarter.  In fact,
there are a few non-default completion styles which will be even more
aggressive than the above miracle.

IOW, maybe your problem was already solved?
