Possible bug in filename completion

[Anne Dudfield]

I posted the following to gnu.emacs.help:

I have a directory ~/etest containing the following files:

blah
blahblah
blah-blah
blah-1

If I C-x C-f and navigate to this directory, then hit space ONCE, I
see in the minibuffer:

Find file: ~/etest/blah

If I hit space again, I see:

Find file: ~/etest/blah-

If I hit space again, I see that, plus the completions list: blah-1
and blah-blah. It seems to ignore the files without dashes in the name.

Version info: 21.3.1 (i686-pc-linux-gnu, X toolkit) of 2005-01-24 on btinstall

This behavior happens whether or not I use my init file. I've done a
great deal of internet searching and can't find any mention of this
behavior, or if there's a way to tweak it to get the behavior I'm
expecting.

Let me know if you need more information.

thanks,
Anne
