And here is an updated test, including a couple of suggestions Stepan
made off-list.  Also, a bug fix for this test:
|   10: tools.at:497       autoupdate

which fails otherwise, when Stepan's fix is applied.  It would be useful
to apply this patch along with it.

Cheers,
Ralf

        * tests/tools.at (autoupdating AU_ALIAS): New test for AU_ALIAS
        `$#' bug.
        (autoupdate): Updated to match AU_ALIAS fix.
