But you already did! :)

Okay, let's use them anyway. And I'd like to move the "extend" and
"vacuum" procedures to the reading and writing of the newsrc.eld file,
so the rest of the code can forget about it. I'll leave the setter
macros in place, and continue to accept (and ignore) an EXTEND argument,
so other people's code continues to work.

I'll look at it some more, and see if I can come up with some tests.
