[PATCH 1/1] git: update to v2.13.2

From: Christian Hesse <mail at eworm.de>

Update to git version v2.13.2: With commit 8aee769f (pathspec: copy and free
owned memory) the definition of struct pathspec_item has changed with the
expectation that pathspecs will be managed dynamically. We work around this
a bit by setting up a static structure, but let's allocate the match string
to avoid needing to cast away const.

Updated a patch from John Keeping <john at keeping.me.uk> for git v2.12.1.
