Yes, the usual config and include rules apply; the patch just selectively
ignores the include based on the subsection regex. So if you put the
magic include in your ~/.gitconfig, anything in the repo's .git/config
will override it.

But that also means the usual restrictions apply, too. There is no way
to "unset" a variable as if it had never been specified in the first
place. And multi-valued variables will always append (e.g.,
remote.*.fetch).

The matcher is a regex, so depending on how tortured you want your regex
to get, you can probably exclude a particular directory with that. :)
