The changelog says why:

    + Allow an explicit empty changelog entry to be passed on the command line
      to allow non-interactive changes to the distribution and urgency without
      adding a changelog entry (Closes: #442267)

Is what you're looking for a valid changelog stanza that doesn't
contain an actual message? If so, would "dch ' '" suffice? (It doesn't
add a space after the "*", and I can't remember if that's intentional,
but it _does_ produce a changelog that dpkg-parsechangelog is happy
with.)
