Ok.  This works for me.  Docs are not updated.  That would push me
over the 10 line limit. ;^)

Now we can easily add other options, like %s for stylesheets or
whatever.  Maybe something like %p to set parameters. (As in the
--stringparam option to xsltproc).

What would be cool is a way to allow the user to *add* custom spec
chars to the default set. (hint hint)
