Thank you for the reference -- I can't say whether closing issue #339 as
WONTFIX was justified or not, but it certainly seems inconsistent with
Jaben's earlier experience (to my understanding), i.e. that git did
expand the glob.

Jaben, can you please answer that? (One version in which it is broken is
2.14.1.windows.1.) Can you perhaps ask your teammates about their
git/windows versions (assuming the *.patch glob is expanded correctly
for them)?

Thank you, Jonathan,
