Drat, I even tried to avoid that conflict, but apparently I thought
the letter that comes after 'n' is 'n'!
Does this fix it?

Hmm, I think the [A-Zo-z] glob depends on the locale's collation
order, maybe it should be just [o-z] since we don't have any symbols
matching std::locale::[A-Z]* anyway. That's something else to clean up
later.
