Still true (although I frequently rewind my personal repo, so you may need
'git reset --hard FETCH_HEAD' instead of 'git merge' to avoid dealing with
conflict resolution as I tweak and rebase the series).

For the record, I did verify that with this patch, 'make distcheck' still
passes, and that the resulting tarball had files, and not symlinks, so the
end client should see no difference in behavior.  It only affects
development from a git checkout.
