Oh, DUH!!! Why didn't I think of $_GET['q'] before?

I'm so used to working with "clean URLs" that I forgot about that GET parameter
lurking under the covers. Thanks for the "whack on the side of the head." :-)

I thought about doing the arg() things you suggest, and I knew it would work,
but I wasn't sure if it was considered the "right" way to do things in Drupal,
in case some future version changes the URL structure.

I'll go with this approach, but I'll make myself a boolean function so that
the "am I in a node?" question is isolated from the rest of my code.

Thanks for the tips. :-)
