This is where we disagree and I don't think either of us will change our minds. My take on it is that this breaks an API in a -stable branch and is adding new functionality so it *should* be added as a new flag. Using a slight variant on your ls example, your approach is like adding the ability to find out what the inode number is by adding a new column to the output of "ls -l". But they didn't do that, they added the -i flag. If they had added it to the output of the -l flag anyone parsing the "ls -l" output in a script would need to accomodate the extra field. IMHO that's acceptable in -current, not -stable and IMHO the new information should go in as a new flag. Your opinion is obviously different, doesn't look like that will change. -- Ken Smith - From there to here, from here to | kensmith@cse.buffalo.edu there, funny things are everywhere. | - Theodore Geisel |
