`*-change-functions` should not modify the buffer (we could try and
enforce this, tho in my experience those that do will get punished
pretty quickly already), so the only cases I can think of where "a
function that changes a buffer can be called from another function which
changes the same buffer" is when both of those functions are in our
C code and we should have enough control to fix those cases.

All sophisticated-enough users of `*-change-functions` rely on this
(and come with sanity checks to detect the problem and fallback on an
expensive recovery when needed, because indeed we tend to break our
promises 🙁).
So we really should try and fix those.
Alan did convince me that we should treat them as bugs and that we
should try and fix them.
