Fwd: Git 2.8.1 fails test 32 of t7300-clean.sh, breaks profile build

[Jan Keromnes <janx@linux.com>]

Hello,

I tried running a full profile build of Git 2.8.1, but it looks like
test #32 in `t7300-clean.sh` fails:

Commands:

> curl https://www.kernel.org/pub/software/scm/git/git-2.8.1.tar.xz | tar xJ
> cd git-2.8.1
> make prefix=/usr profile-install install-man -j18

Logs of test-suite that fails:
