CC-ed some folks who have interest in safe.directory and/or have looked
at the safe.bareRepository series.

Thanks for the report. As the author of the series in question, this
wasn't an intended change.

Protect config, as implemented in 5b3c650777 (config: learn
`git_protected_config()`, 2022-07-14), reads from a hardcoded set of
file paths without considering "include"s, so this bug is not surprising
in retrospect.

I believe this can be fixed by replacing this implementation with an
invocation to config_with_options() (which knows about "include"s)
should be adequate to fix this.

I'll prioritize a test and a fix for this.
