Thanks for playing: the code tries the case-non-folded name first and
only if that one fails, does it fallback to case-folding, so the above
examples all work correctly.

I.e. enabling auto-mode-case-fold only changes the behavior in the case
where the buffer would otherwise be put in fundamental-mode.  So the only
possible downside is if the mode chosen by auto-mode-case-fold is worse
than fundamental-mode.
