I think a subshell is implicit in backquotes.
So I don't think this patch should be required.

I'm assuming you're doing this on Windows?
What shell are you using?

It is (mostly) harmless to apply this patch, but if we really need it
then we need to audit the code to make sure this construct is used
everywhere, and then we need to add something to maintainer-check so
that we don't inadvertantly reintroduce the problem.
