Add a Makefile to run subtree tests. This is largely copied from the standard test suite with irrelevant targets removed and some paths altered to account for where subtree tests live. Signed-off-by: David A. Greene <greened@obbligato.org>
Please read git-subtree.txt for documentation. Please don't contact me using github mail; it's slow, ugly, and worst of all, redundant. Email me instead at apenwarr@gmail.com and I'll be happy to help. Avery
