One other way I'd thought about doing this is via a post-update hook
that would read the configuration from an object in the repo into a file
cgit could read, but I didn't want to write out into .git/config.

That might be one way of achieving compromise -- support per-repository
configuration that users themselves can push, but make it up to the
server administrator to set up hooks so that the config gets written out
into .git/cgitrc (or repo.git/cgitrc) for cgit to consume. In my mind,
it was a note attached to the initial commit of the master branch, but
it can be any object that post-update can access and write out.

This way cgit doesn't need to rely on git to read this data, as it's a
regular config file inside the git dir. The post-update hook can also do
any sanitization of config parameters it deems necessary.

Does that make sense?
