Applied, thanks. Funny how many pesky regressions get found by testing 
with different set of specs... (eg in Fedora-world, %changelog is 
"always" the last section in which case this bug doesn't trigger)

FWIW, I'm going to release 4.9.1 in nearish future to plug these 
annoyances so your patch-count doesn't blow up through the roof :)
