Err... `compset -P "*"' does that, but it leaves you with an empty
$PREFIX, of course, which is probably not what one wants.

The problem is that we check the quoting stuff at the very beginning
of the completion code -- and detect only quotes at the beginning of
the word. So what we could get to work is completion of

  $ perl '-V:<TAB>

but not with the quote after the colon. That's done with first calling 
`compset -q', then the `compset -P'. Getting quotes in words to work
is to hard to make me try it (all kinds of nasty interactions with the 
lexer). But maybe calling first `compset -P' and then `compset -q'
should have the same effect as the other way round... I currently
don't remember why it behaves the way it does.

Bye
 Sven
