I'm going to voice my dislike of side-effects in Parse functions one
last time (I think that a function called "...Parse" should interpret
the data it's given, not add new data) and suggest that the Mac
generation should always be done in the caller when needed rather than
passing a strange flag down to the parser. (I know the parser was
already generating the MAC; I think it should be changed to *not* do
that) (or at the very least the flag shouldn't be "on == don't do
something extra", it should be "on == do something extra").
However, if nobody else expresses agreement with me on that, I'll
consider myself outvoted, and keep quiet during the next version of the
patch (based on danpb's review of PATCH 4/5, it seems there is going to
be another round anyway :-)
