That's pretty interesting; it seems like a bash bug to me.  I don't
think it would matter, as consecutive slashes are always condensed to a
single slash when a file is being opened, etc, but it's still odd.  I
noticed it only does this with exactly two slashes, and that it also
shows up in the output of 'pwd' :

jeremy at jeremy ~ $ cd /var
jeremy at jeremy /var $ cd //var
jeremy at jeremy //var $ pwd
//var
jeremy at jeremy //var $ cd ///var
jeremy at jeremy /var $ cd ////var
jeremy at jeremy /var $ rpm -q bash
bash-2.05b-34
jeremy at jeremy /var $ cat /etc/redhat-release
Fedora Core release 1 (Yarrow)

--Jeremy, a little curious too.
