Hi Tom,
I think you can go ahead and commit 0001-0003. For 0003 I do admit
being confused why valgrind had a problem with progname...
FWIW, I also took a quick eyeball check of the coverage output for
preproc.y looking for untested non-error branches that do things that
are not covered elsewhere, and I didn't notice any. Some places
allocating new connections are not covered, which should be handled by
0003.
