And which of course you don't check anymore. So any statement about "all
tests passing after these patches" is not worth much.

So NAK in this form, but perhaps if/when my year-old patch gets picked
up (or you could include it in the series) we can talk about eliminating
the check for past-nul-before-end-of-buffer writes.
