Hi,

While working on some Zsh completions I happened to notice the following
when using this kind of completion (extracted ~minimal example follows):

#compdef foo

_foo () {
  local curcontext="$curcontext" state line expl ret=1
  declare -A opt_args

  case $service in
  foo)
    _arguments -C -S -s \
      "(- *)"{-h,--help}'[show help]' \
      "(-h --help)"\*{-F+,--filename}'[specify filename]:file:_files' \
      '*:host:_hosts' \
      && return 0
  ;;
  esac

  return ret
}

_foo "$@"

These work as expected:

$ foo -F <TAB>                   - getting filenames
$ foo -F<TAB>                    - getting filenames
$ foo <TAB>                      - getting hostnames
$ foo localhost --filename <TAB> - getting filenames
$ foo localhost -F<TAB>          - getting filenames

But here's the unexpected case:

$ foo localhost -F <TAB>         - getting filenames and hostnames

This is with 5.4.1. What could explain this behavior, any suggestions
how to fix this (so that in the last case would get only filenames)?

Thanks,
