process::ExitStatus: Discuss `exit` vs `_exit` in a comment.
As discussed here https://github.com/rust-lang/rust/pull/88300#issuecomment-936097710 I felt this was the best place to put this (rather than next to ExitStatusExt). After all, it's a property of the ExitStatus type on Unix. Signed-off-by: Ian Jackson <ijackson@chiark.greenend.org.uk>
