We do change this in GDB whenever we need to. Jan has a patch ready
that will introduce version 5.
But... first, we try not to change it, because changes are disruptive.
Second, a change requires a version bump and an update to the
documentation (in the past this was just a comment, but in the future it
will require a change to gdb.texinfo).
