Murks in _complete. It didn't use the return value, but tested
$compstate[nmatches], so it called it for every match spec, then
returned non-zero even though the message was added and _main_complete 
called other completers and before that reset the flag that says that 
a message was added so that you got the message and the `warning' that 
there are no matches (the line with the `...').

As it says: _arguments, which has to find out if you want to complete
options or only arguments or whatever.
