With a little help from `awk' this was relatively easy to build, so I
thought I just try to make us make a decision.

This is `User/_pbm' again, but containing mostly the stuff from the
`Pbmplus/*' files. I like the improved speed on startup and I think it 
still is readable enough. Also note that with `_pbm' it is no problem
to allow users to override this with their own functions for such
commands because it is a post-pattern function anyway, so we get that
for free. If you have a special function for `pbmfoo' or whatever,
that will be used instead of `_pbm'.

Bye
