Actually, it's pretty straight-forward and I think the resulting code is
cleaner. Note that we do have to use a real expect_success because of
the side effects. That does increment the test counter. IMHO that's not
a big deal, but if we're concerned it wouldn't be too hard to add a
non-lazy prereq block.

Patch is below (I pulled GPGSM into its own block, which involved
reindenting; view with "-w").
