logical-pathname-translations question

Hi all,

I have the following code:
((setf (logical-pathname-translations "foo") '(("**;*.*" "./**/*.*")))

which basically maps foo to the current directory. It works for all  
files and directories as long as their names do not contain spaces or  
underscores. Am I missing something here? How do I also make it work  
for files and directories that do contain spaces and underscores in  
their names?

I'm running ACL 7.0 (ansi mode) on Win XP Pro.

Any help is greatly appreciated. Thanks!
