this comment runs the risk of bit-rotting.  if someone moves that file in
WebCore, they surely won't think of fixing this comment!  that said, this
comment is definitely useful as one would like to know where to look for the
various log channel definitions.

anticipate most users will already have seen what they want in the WebKit
source.
