OTOH this has never worked on Python 3, so it's hardly an important fix.
If it's delicate enough, we may prefer to only ship it in 3.8.

PS : it's the first time I encounter "/dev/stderr".  Apparently it's a
Linux-only symlink to "/proc/self/fd/2", i.e. the current process' file
descriptor number 2 (which is conventionally the current process'
stderr stream)!
