Oh. Stupid me... I thought I had tried this once and it didn't
work. Seems like I made some other mistake then. Sorry.

Ah. I hadn't thought of something comparable to `-f'. That just says
`this is a filename, do the file-tests if needed (in do_single())'. We
could add an option that says `this is a parameter name, do the
file-tests for it if AUTO_PARAM_SLASH is set'. We would have to get
all the prefix/suffix stuff right then (and define how they work in
that case), but it should be possible... I just don't know if this is
probably to special a case.

Bye
 Sven
