All this is so disgusting... sigh.

That code is there to turn turn null tokens inside parameter expansions
into their original forms (single or double quotes) so that later code
can use them correctly because they won't be removed in the following
loop.

Unfortunately, this will only be done if we are completing *inside* the
parameter expansion (the parameter name). I'll have to try if it is
correct to change that part of the code to re-install quotes anywhere in
a parameter expansion in the word (well, it sounds right, doesn't it?).

But even with that there's still something fishy with list-expand which
I haven't any further into yet. And with _expand and functions that call
it:

  beta% e=( '${(M)${(f)"$(<x)"}:#*2*}' )
  beta% echo ${(e)e}
   
  beta% echo ${(e)~e}
  111 222 333
  beta%

Oh well. Anyone interested in fixing that?


No patch yet...

Bye
