Agree the name is bad. I should probably do a cleanup of the grammar at some
point, but I don't think it's a top priority right not.

Sounds good. I'll close this as invalid (not sure what the keyword is for "no
longer an issue"). And we can file a new issue if this turns out to be a
problem again.
