Two builtins `complete' and `compgen' with almost the same options,
functions starting with underscore, -[PS] options, COMPREPLY, arrays
holding names of stopped jobs and functions, etc.

`compgen' is lightly different from what was our `compgen', it
obviously just outputs the possible matches. But then -- the name.

Are we being monitored? ;-)

Unfortunately I couldn't any more info...

Bye
 Sven
