Do we have a convenience function that says whether we have a match in
auto-mode-alist?  `set-auto-mode--apply-alist' seems to be the closest I
can find, and...  it's not that close.  :-/  But I guess it could be
refactored out of there.

We have a chicken/egg problem, though.  Adding `diary-file' to
`auto-mode-alist' would be fine, but we calculate that in calendar.el,
so people not using the calendar won't get the mode.

We could move diary-file out of calendar.el and put it in...
bindings.el or something, though?
