I have another idea, maybe we can take it even one step further: Why
don't we let the helper functions output to stdout instead of adding
to COMPREPLY directly?  A suitable prefix for this function range
would then be `_compgen':

- _compgen_known_hosts
- _compgen_filedir
- _compgen_pc_ids
- ...

Rationale:

It makes helper functions less coupled, thus better.

Outputting to stdout is in analogy with bash's `compgen'.

Outputting to stdout is in analogy with normal bash function
behaviour: input via function parameters, output via stdout.

The `_compgen' prefix would also serve as a start for letting
bash-completion functions reside in some kind of `comp' namespace in
order to make it less likely for bash-completion functions to clash
with user functions 'out there'.

What do you think?
