No, I don't think we want to physically copy anything we don't have to.
(Before the commit I mentioned upthread, we were actually doing it more
or less as you suggest, and it was messy.)

I'm not really concerned about the current behavior of putting transformed
input/output files into sql/ and expected/.  Only experts are likely to
be creating files requiring transformation at all (and even the experts
prefer to avoid that, because they're a PITA).  So I am not very worried
about duplication of file names between eg input/ and sql/.  But I don't
like handling VPATH by introducing confusion between --inputdir and
--outputdir.

It does strike me though that some of your pain is self-inflicted: why
did you think it was a good idea to create both test/sql/ and sql/
subdirectories?  What's the point of test/ at all?  It's certainly not
part of the standard layout for a contrib module.
