I went ahead and applied this (with some cleanup).  I don't see a very
good reason why the prefix/suffix shouldn't be shown in the completion
data --- after all, that *is* what it's going to type for you.  In any
case, preventing that would take some fundamental hacking of the
readline interface; which would be way more work than it's worth,
and probably not very portable across the different versions of
readline either.  So I think we should just be happy with this
behavior.
