Yeah, I did that intentionally, thinking that the old behavior was
confusing.  We can certainly discuss it though.  I'd tend to agree
with your point that \p and \w should print the same thing, but
maybe neither of them should look at the previous_buf.

I don't really agree with this.  The fact that it used to clear both
buffers was an implementation accident that probably nobody had even
understood clearly.  ISTM that loses functionality because you can't
do \g anymore.
