1. Fix zsh for DirectiveNoSpace and DirectiveNoFileComp …

   Fixes spf13#1211
   
   When handling ShellCompDirectiveNoSpace we must still properly handle
   descriptions.  To do so we cannot simply use 'compadd', but must use
   zsh's '_describe' function.
   
   Also, when handling ShellCompDirectiveNoSpace we cannot assume that
   only a single completion will be given to the script.  In fact,
   ValidArgsFunction can return multiple completions, even if they don't
   match the 'toComplete' argument prefix.  Therefore, we cannot use the
   number of completions received in the completion script to determine
   if we should activate the "no space" directive.  Instead, we can leave
   it all to the '_describe' function.
   
   Fixes spf13#1212
   
   When handling ShellCompDirectiveNoFileComp we cannot base ourself on
   the script receiving no valid completion. In fact,
   ValidArgsFunction can return multiple completions, even if they don't
   match the 'toComplete' argument prefix at all.  Therefore, we cannot use
   the number of completions received by the completion script to determine
   if we should activate the "no file comp" directive.  Instead, we can
   check if the '_describe' function has found any completions.
   
   Finally, it is important for the script to return the return code of the
   called zsh functions (_describe, _arguments).  This tells zsh if
   completions were found or not, which if not, will trigger different
   matching attempts, such as matching what the user typed with the the
   content of possible completions (instead of just as the prefix).
