Re: PATCH: 3.1.5-pws-8: using pattern completions

There are two more problems: when dumpin patcomps we need to make sure 
the elements are not split (they contain at least one space) and the
pattern-function files should not quote the patterns.

It's in the `|| return 1'. If a pattern function returns non-zero, the 
other patterns and the completion for the command are not tried.

A few open questions:

- The return non-zero convention is intended as a replacement for
  `compctl -t'. I didn't document it because I'm not sure if this is
  the right way to do it.
- Due to getting the patterns automatically from the files they are
  not sorted. This may be an argument in favor of the simplified
  processing I used in the `Comp' example directory.
- We probably should also completely remove the completion-array-handling.
  This would make the code much cleaner, would allow us to get rid of
  the callcomplete-trampoline, and would allow us to call dump anytime.

(I'd like to clean up the whole example code, anyway: use only one
leading underscore, but use it for all functions and aliases, add the
`__if' stuff I described yesterday, remove the aliases, etc. Dunno if
I find the time to do this today, though.)
