Subject: 23.3.50; conf-mode-maybe rule grabs config.h.in
Date: Mon, 25 Apr 2011 12:42:03 +0100

The current rule in files.el for conf-mode-maybe grabs config.h.in,
which should instead go through the .in-stripping rule and end up in
c-mode.

From the comment for that rule, it seems that the only time it should
allow an extra (middle) suffix is when that is .local, so changing it to
something like

     ("[/.]c\\(?:on\\)?f\\(?:i?g\\)?\\(?:\\(\\.local\\)?\\.[a-zA-Z0-9_-]+\\)?\\'" . conf-mode-maybe)

i.e. removing period from the character class at the end and adding an
explicit optional .local before it, should work.

The comment actually says that config.foo should also work.  I've
committed a different fix based on reordering the rules.  Thanks.
