Agreed --- attached patch applied.  I also noticed that we sometimes
test for -? then --help, but other times do things in the opposite
order, and the same for -V/--version, so I made that consistent.

However, I also noticed that while we document -? before --help, we test
for --help before -?, and the same for -V/--version.  Should I make
those even more consistent by always testing for the single-letter
option first?
