I assumed so was yours.

No, 'auto' does NOT behave as 'nil' on Windows, not in general. It
only behaves as 'nil' when Grep is invoked as an async subprocess,
because Windows uses pipes, not ptys, to do that. Any system where
'process-connection-type' is 'nil' will exhibit this behavior.
Moreover, even on systems that do support ptys, Emacs will use pipes
if "all ptys are busy" (citing the ELisp manual).

We could, I just don't know if we want to. But I don't object to such
a change.
