Hm, no parameter? Even if ${(t)compstate} yields `association-local-special'?

We can use the conditions, e.g.:

  if [[ -prefix * ]] 2> /dev/null; then
    # completion active
  fi

Or should we change compadd to return `2' in $? when completion is not 
active? Or `1' there, but `2' if no matches are given, so that we
could do

  compadd 2> /dev/null
  if [[ $? -ne 1 ]]; then
    ...
  fi

? Dunno.

Bye
 Sven
