Yeah, that's the user I'm concerned with in this case, since _we're_ the one
switching the library. I'm imagining users with scripts written by a
sysadmin or grad student fifteen years ago which happen to use `grep -P`
suddenly and mysteriously doing the wrong thing.
Eh, seeing as the grep(1) manual page itself still declares the option
as experimental, I think people using it *should* be aware of the
possibility of slight changes in behavior.
G'luck,
