Well, these are two additional changes on top of the one I posted though
and can easily be addressed in the future.  Meanwhile, a combined build
with maintainer-mode enabled will cause spurious changes to generated
files, and the patch is pretty minimal in that it fixes the issues but
doesn't change semantics otherwise.  So, ok to commit to src?
