Over the years, I have convinced myself that there is pretty much no way
to put events back on unread-command-events for reprocessing without
introducing corner case bugs.

For this reason I introduced the `set-transient-map` function, which can
be used in some cases to avoid "read + unread".

Anyway, my point is that maybe a better fix is to try and understand why
Calc does a read+unread and then figure out a way to get the same end
result without needing to read+unread.
