Re: [Bug-readline] directory_completion_hook interacts with tilde expansion

[Stefan H. Holek]

I have no objections to the expanded directory name being passed to  
the hook ;-). Thing is, however, that when a directory_completion_hook  
is set (even if it does nothing), the expanded directory name is also  
inserted into the line. I would not expect the latter when I (as a  
user) have set expand-tilde off.

The relevant rl_filename_completion_function snippet is:

      if (rl_directory_completion_hook &&  
(*rl_directory_completion_hook) (&dirname))
        {
          free (users_dirname);
          users_dirname = savestring (dirname);
        }

Thanks,
Stefan
