Perhaps calling it something like --permissions would be good (IMHO,
that is more descriptive than "--shared" for "git init"). Then both can
respect it, and "init" maintains "--shared" for backwards compatibility.
Calling it --shared-repository does match the config name, but I do not
find that name especially descriptive. But perhaps it is good enough,
and consistency with the existing name is certainly a plus.

Yes. This is as-documented for "clone -c", which claims to act after the
repository is initialized. That being said, I think it is less confusing
for the user for them to take effect as early as possible, so the user
doesn't have to worry.
I cannot think off-hand of any case where the user would actually want
the delayed effect.

Yes, I think this is simply a bug in 84054f7 (clone: accept config
options on the command line), which assumed that any effects it had
would be picked up by the git_config() call.

If we call check_repository_format() again, we will pick up the new
config. But I think we would still have to go back and fix the paths
created by init_db.
It may be cleaner to teach init_db to add the initial config (and
optionally add "init -c" for testing, though I do not think anyone
particularly cares in the real world).
