I don't know the specific method you're using to populate fake-files,
but my suggested approach is to use "zstyle -e" to filter the value
before returning it to the completion system.  Remember completion is
designed so that the shell functions typically collect all potential
matches for a given situation and then leave it up to the internals
to filter them against the command line.

So if you are able to push some of that filtering into the functions
by use of hooks like "zstyle -e", you can optimize much better than
the generic internal filters are able.
