Apologies...quite possibly a crop gone awry...your name *was* the one at
the top of the quote/requote/rerequote sequence, but I may have not have
"chopped" low down enough in the chain, or it's possible that my
Thunderbird installation is not properly set up to properly attribute the
most recent quote.

My response, in the message above, was not in response to your test, but
to Kevin's note about not leaving commented lines around.

While I'm looking at this, though, my earlier assertion that # wouldn't
work as a comment in inittab, at this level, would appear to be incorrect,
as well, given that *all* of the comments at the top of the file start
with a #.

I'm still doing some digging.
