I'm not a maintainer, but you'll probably be asked for some tests of 
this (really useful) feature.

I don't think you need to worry about removing any convenience 
variables you create, each .exp test file starts gdb afresh, 
and sometime (look for clean_restart) gdb is restarted within 
a single .exp file.

For this feature you can probably get away with just adding some 
new tests to the end of the completion.exp file, I've included an
example test in this mail, but you'll probably want some more.

thanks,
Andrew
