completion for {foo,ba/baz

[Dave Yost <Dave@xxxxxxxx>]

It seems to me that zsh completion should work on an argument that has a { without a closing }.

So, tab on
  {foo,ba/baz
should produce
  {foo,bar}/baz
and if the only two things in the directory are foo and bar, then tab on
  {foo,/baz
or 
  {foo,}/baz
should produce
  {foo,bar}/baz
