PATCH: Re: Backticks and other tricks

[ moved to -workers ]

I wrote:

Since the filters array is to be used later it should of course be
before that `if' (or stored in a global _ecasound_filters array).

And I forgot to say that the values can be retrieved with



as in:

  if [[ -n $state ]]; then
    local what=${${(M)filters:#${state}:*}#*:*:} pat
    if [[ $PREFIX = ${~pat}*, ]]; then
      _message 'too many parameters'
      while [[ -n $pat ]] && ! compset -P $pat; do
      _message "${${what%:*}##*:} in ${what##*:}"

(I guess something like that was what Mario was aiming at).

Anyway, what I really wanted to say (and that's why it's on -workers): 
if you try this with a `&& return 0' after the `_arguments ...' you'll 
notice that competion after, e.g. `-ef1:' yields nothing.  That's a
result of the change that removed the 300-return-value -- it has added 
the option itself and hence `_arguments' returns zero.  Ugly.  Very.

I can't think of a completely satisfying solution now.  Taking the
current option from the arrays of known options isn't good, because
then one wouldn't get offered an option `-foo' if that is already on
the line and there are other options starting with `-foo'.

So for now let's use the patch below.  It adds the options only if
there is no `->state' action to use or if we are not in the same word
after the option.
