Hello everyone.

I'm trying to write a somewhat feature-full completion function for the new=
=20
bazaar 2.0 (aka bzr) revision control system.

The bzr developers have recently added some command line functions that can=
=20
list files with NULL terminators, just like find.  Unfortunately, I can't g=
et=20
the completion functions to work correctly.

my completion function for add looks like this (in a nutshell):

  (add)
       _arguments $helpArgs \
       '--no-recurse[do not recurse into subdirectories]' \
       '(-q)--quiet' \
       '(--quiet)-q' \
       '*:unknown files:_unknownFiles'
  ;;

_unknownFiles() {
    local fileList;
    fileList=3D($(bzr ls --null --unknown))
    compadd -af fileList
    return 0
}

When I test it, I get: this

% cd repo
% touch "foo bar" baz zed
% bzr add [TAB]
     bar  baz  foo  zed

It's somehow splitting "foo\ bar" into "foo",  " ",  "bar".  I seem to be=20
missing something obvious.  Can anyone help?
