The following issue left my terminal in a weird state.
Is this a bug in the repository, or a bug in git 2.43/46?

set -ex
pushd /dev/shm
test -d x.git || git clone https://github.com/intel/linux-sgx.git x.git
cd $_
git checkout -b $PPID.$$ a53adeaab7a8176fabb415bfcdf6d29fe4060678
d=external/ippcp_internal/inc
git log -p -b -B -w --stat --follow "$d" |& tail
cd $d
git log -p -b -B -w --stat --follow . |& tail


Thanks,
Olaf

Definitely a bug in Git, since we're hitting a BUG(). Looks like it
reproduces with just "-B --follow" on the path in question. Bisecting
leads to 9db2ac5616 (diffcore-rename: accelerate rename_dst setup,
2020-12-11). +cc Elijah.
