ajaksu2, I think you just changed the status of this to "test needed".  
I don't think a unit test for this functionality is possible if that's 
what you mean, as it is an interactive feature involving readline 
completion at the interactive prompt only.

It's been a long time since I posted this patch, and I don't really 
mind if you just close the issue.  There obviously hasn't been a lot of 
interest since 2003.
