If you're curious what the fix looks like, it's in:
https://github.com/peff/git jk/config-repo-setup
The actual fix is in the final patch, but it needed a lot of preparatory
work to avoid breaking various programs that made bad assumptions (and
in the process, I uncovered a ton of other minor bugs).
This is just a preview in case you're interested, for two reasons:
1. I literally _just_ put the finishing touches on it, and it's
extensive and tricky enough that I really should give it one more
proofread.
2. There may be other related fallouts from the bug related to running
"git init /path/to/foo" when "/path/to/foo" already exists (and in
that case we _do_ want to read its config, but not the config from
an existing repository). This may all just work fine, but I need to
think about some tests.
