I'd like to hear opinions of others.  Meanwhile, having the proposed
convention spelled out in the manual would be good to make sure we are
all on the same page regarding the issue.

As for the issue itself: cannot we detect the separators in some more
robust way, one that doesn't depend on how they are named?  And if
that's not feasible, perhaps allow anything that has "separator" in
its name to be considered a separator?

Thanks.
