The key problem is with quoting.  We just introduced a tweak so that you
can now do
  echo ${${(f)"$(ps)"}% *}
since an unquoted $(ps) does word-splitting on all spaces.  The traditional
way of doing this was
  echo "${(@)${(@f)$(ps)}% *}"
but that's more cumbersome.

`correct' isn't all that flexible at the moment.  There ought to be a way
of fixing it internally.
