Probably not a simple solution, since as the article points out it would have to be done in a way that wouldn't break existing taginfo scripts. The CVS gurus on this list would have more insight into that.

Also, the poster in the article mentioned that he didn't need the fourth argument. However, stdin is also a buffer somewhere in the system, and if a filter doesn't read all of it CVS can fail with a 'broken pipe' error (see the comments about this in the loginfo section:
