Either you're misunderstanding the case I'm trying to address, or I'm
misunderstanding what find_toplevel_char is searching for.  This is
the kind of confusion that generates dozens of mail messages, but
would take two seconds to straighten out in person.

Since the patch is approved either way (with appropriate changes to
the comment above find_toplevel_char), and I think we all basically
get what's going on, I'm not going to pursue this further.
