It compounds the flaws.  The original one was not barring an all-digit
filename from being a folder.  Code just didn't check as much back then.

We should state what makes a wise folder name,
e.g. /^[[:alpha:]][-_[:alnum:]*$/ in the user's locale.

We report the problem better in other cases.

    $ td
    /home/tmp/1719392294.254317947
    $ cp `mhpath .` 1
    $ scan +.
