I would like to propose promoting 'contrib/rerere-train.sh' to one of the following: 1. A builtin c command 'builtin/rerere-train.c' 2. To the top level directory as a built in script 'git-rerere-train.sh' I have recently found myself writing scripts using 'contrib/rerere-train.sh' and I wish it was built into the command. This would make it easier to use rather than having to find it on different platforms. I think it could also benefit from some documentation. I am trying to gauge the interest in this change before spending some time on working on it. I would also appreciate feedback or alternative approaches to what I have suggested. Thank you for your time. Thanks, Tom Miller
