      What's the reason for this?  The code doesn't appear to
be Unix or
 Windows-specific.  I've been writing code that uses `concat', and so I'd 
 like to know why it's not portable. 
Because there could be system where this is not a valid file name.
While this works on Windows, Unix, and VMS, it may not always work.

`expand-file-name' will always work, no matter what system it is on.
