[PATCH] provide better committer information to commit-tree.c
Here's a small patch to commit-tree.c that does two things: - allows the committer email address and name to be overridden by environment variables (if you don't like the environment variable names I've used (COMMIT_AUTHOR_NAME, COMMIT_AUTHOR_EMAIL), feel free to change them.) - provide the proper domainname to the author/committer email address (otherwise, my address was only showing up as from the hostname.) This allows people to set sane values for the commit names and email addresses, preventing odd, private hostnames and domains from being exposed to the world.
