report to message handler whether evaluating cumulatively

we evaluate prf files precisely even when the pro file is evaluated
cumulatively. the message handler should know the mode a message is
reported in.

this just syncs up with qttools/08d0cb6f8e90a818bf6d3bec7a6d00f16419b8c0
and qttools/ea1a5c3534f089c0e704808a0fb029eda8f753b4 without
user-visible effect.
