Damn that w32-downcase-file-names option!  Why are people still using
it in the year 2013??

Thanks; fixed in revision 111711.

Hm.  FWIW, I wasn't even aware of that option.

If it is not so appropriate now (or ever?), why not tweak the doc string to
suggest that?  Reading the doc string, you can easily get the impression that
you might want this to be non-nil.

IOW, if you wonder why people are still using this in 2013, maybe take a look at
what Emacs tells users about it.

If we don't want people to use it, then let's mark it obsolete.

I will start a discussion about this on emacs-devel.  Let's see how
many people will holler.

I don't remember why I use it (something to do with RCS I expect), but
I'll stop, and report any issues if they surface.

I'd be curious to know how RCS is related to this.  I use it myself.

Thank you.
