   I seem to have found a file name globbing bug, whenever the string
   to be expanded starts with a / the / seems to be dissappearing in
   the attempted expansion.  For example, if I am in directory /bin
   and do

   ls /t*

   I get tar tee test time tp true (in the current dir)

   instead of
      tmp tp	(in /)

I came up with this fix for the problem.  Note that even with this fix
bash still behaves differently than sh and csh.  Try

	echo /tm* //tm* ///tm*
and notice that one / is removed from the last two examples.
