Well, the only use of an isolated `Q' (as would be useful for marking)
is in gnus-sum.el in the definition of gnus-sparse-mark.  That
variable is then used in gnus-build-sparse-threads and
gnus-summary-limit-to-unread.  But I can't offer any explanation for
what Gnus thinks it's doing with that mark in those functions.

Is the article in question actually missing, or is there some kind of
bookkeeping error happening in nnml?

Anyone else got a cogent view of this?
