I don't think I like the solution for the second issue, since it is a
backward-incompatible change.  It is not at all obvious that not
updating a proced buffer which isn't shown in a window is TRT.

Why cannot we simply save and restore point across updates?  If the
old value of point ends up in a slightly different position (because
many processes have died, for example), that is not a disaster.

Alternatively, record the process on whose line point was before the
update, and try to find the same process after update.
