I was actually trying to get a saner behavior of process_acknowledged
(which is currently called sort of in lightning storm frequency and
makes dealing with things like tweaks applied by the Tweaks_engraver at
Score level pretty hard).

Except that my attempts to sanitize that all crash.  In the process of
finding out what may be the reason for that I tried tracking down what
the origin_context thing is used for, and that was surreal.

Patch proposed.  There is something quite similar for Audio but I'll
leave that for later.

Still haven't made progress with my original problem.
