Can you tell why you replaced a literal "*Help*" with a call to
help-buffer? That change was part of your pixel-resizing changes, but
it doesn't sound related to me, and the ChangeLog entry doesn't
provide any explanations to convince me otherwise.
Also, describe-bindings-internal is only called from this single
place, so I see no reason to support some other help buffers. Do you?
