bug#28083: Two patches for grep on Windows, fixing directory recursion and leaking color

[Paul Eggert]

Stephan, I'm following up on GNU grep Bug#28303 
<https://debbugs.gnu.org/28083> dated 2017-08-13, which ends with this 
email from you dated 2019-12-31:

> I'd still like to
> get this patch in, so let's restart. I kept my branch around and the patch
> rebased cleanly (with a trivial merge to NEWS). I'll email the FSF this
> week.

I don't see any record of your assigning copyright to the FSF since 
then, which means your patch still isn't in GNU grep. If you're still 
interested in getting it done please let us know, and we can restart the 
process again.
