Okay, the attached version does it that way.

I also attach some changes for the MSVC build stuff.  I tested it and it
builds fine AFAICT, but it doesn't install because Install.pm wants to
install contrib modules from contrib/ (which seems reasonable) but my
hack adds the src/test/modules/ as contrib modules also, so Install.pm
goes bonkers.  I'm not even sure *what* we're supposed to build -- there
is no distinction in these programs as there is in the makefiles about
what to install.  So if some Windows developer can look into this, I'd
appreciate it.

I'm leaving that problem for someone else to solve.

Argh.  Okay, the attached doesn't move test_decoding either.

I think it's fine anyway -- I'm sure we will come up with a few
additional test modules, such as the one for the commit_ts patch.
