This is trivial enough that I'll throw it in my pull request today.

Hmm, why "as more than", not just "more than"?.
(this note is about the following: the protocol allows adding more than
one byte of flags with use of DIRTY_BITMAP_MIG_EXTRA_FLAGS. Still,
currently this possibility is not used and we assert it.)
