No, we don't have that yet. But we have a completion function for mutt.


Hm, if you have a function to generate the option names you can easily 
use that. I guess the function puts the options into the $reply array
(I'll assume the strings generated include the `-'), so you can do:

  _use_so() { # ;-)
    if [[ $PREFIX = -* ]]; then
      ... # call perl-function-thingy
      compadd -a reply
    else
      _default
    fi
  }

To make this nicer, change the `compadd'-line to:

  local expl
  _wanted options expl option compadd -a reply


Bye
