My guess:  DOS filenames are composed of two parts -- the main part and the
extension.  When parsing filenames, you look for the '.'.  Anything before the
'.' is the main part; anything after it is the extension.  Files ending with '.'
just don't have an extension.

I agree with that, having seen this before, but I am curious... It seems that
such functionality did not get there by accident (I cannot think of a way to
ignore characters in a filename without some _extra_ coding), so it must have
been done for some purpose.  Yet I cannot for the life of me imagine what
benefit this produces, or what fault it would circumvent.  Anyone have ideas
as to this?
