OK, but unlike the static function, being in public interface part
can invite mistakes of using this for things outside $GIT_DIR [*1*].
Let's have "Never use this for working tree directories" somewhere
in its docstring.
Other than that, this one, 24/26 and 25/26 looked fine to me.
Thanks.
[Footnote]
*1* Anything created by this function and everything underneath are
repository metadata and this function must not be used to do with
anything with the working tree, as it is clear with the use of
adjust_shared_perm().
