I broached this topic a while back, but no one seemed to think
that it is a bad idea.

>Is there some easy way to disable the prefix matching in the resource manager?

I just got rid of it in the code; so far it hasn't broken anything.
I suspect it will give me problems with future patches, but I decided
to accept that. Defining BAL (or whatever you like) will get rid of
the substring matching.
