For the record, you can correct the contents of an unpacked grep-2.15 directory by running the following command:
cd grep-2.15 && grep -rl '2\.14.56-1e3d' .|xargs perl -pi -e 's/2\.14.56-1e3d/2.15/g' This changes what grep --version prints (making it 2.15, not 2.14.xxx...) and corrects the few references in documentation. I'll wait a few days and then make a 2.16 release.
