Sorry, I made a silly mistake: the regexp `.*' matches any file, so the
entry needs to be the *last* one in dired-guess-shell-alist-user.  But
then you have to be sure that none of the preceding entries match a
directory.  This will probably be true of any file ending in `.zip',
`.tgz', etc.  If you do have any directories whose names have endings
that could also be used for non-directory files, you could wrap the command
expresion in the corresponding entry in an `unless' form, e.g.:
(".xyz" (unless (file-directory-p (dired-get-filename)) "shell-command") 

Hope that helps.
