Some (but curiously, not all) of the Windows critters are unhappy with
the fact that I removed the extra expected files for the ECPG tests.
In retrospect, the reason is obvious: the ECPG test programs do not
include port.h nor link with src/common, so they're not using our
custom printf, just the platform native one.
I could just revert the ECPG aspects of that commit, but considering
that it seems like everything else works, it's annoying to still need
extra expected files for ECPG.
What I'm now thinking about is modifying the three affected test
programs so that they internally strip the extra zero using the
same logic as in snprintf.c. It'd be slightly more work but
might be worth it in the long run. On the other hand, we hardly
ever touch the ECPG tests anyway, so maybe it isn't?
