After testing a previous patch at larger scale, a performance issue was detected when using git show to locate parent revisions, with a single run of the git show command taking 2 seconds or longer in a complex repo. When the command is required tens or hundreds of times in a run of the script, the additional wait time is unaccepatable. Replacing the command with git rev-parse resulted in significantly increased performance, with the command in question returning instantly.

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
