Hmm... the zsh-mime-setup script is smart enough to get this right if
you specify pdf.bk in ~/.mime.types, e.g.

application/pdf pdf pdf.bk

but unfortunately the main shell isn't:  given the suffix alias pdf.bk,
it only looks for the .bk suffix, so the MIME handler isn't started.
This is probably fixable, although I'm not sure if it's strictly a bug.

If you were able to use a special suffix for this case, e.g. pdf_bk, it
would all work.
