Sorry, but I didn't see any of these emails before sending this
and the subsequent patch email. :(

I can sometimes be away from email for several days at a time (and
then spend days trying to read the backlog - I'm on *far* too many
mailing lists!).

[The internet went black on me last night; I couldn't see anything
outside of my ISP's servers (and not all of those). I also couldn't
get any answer at the support phone number, so I probably wasn't the
only one ...]
