rhg: Sort config files when adding a directory For example in `/etc/mercurial/hgrc.d/` or with `HGRCPATH=some-directory`. Previously files where parsed in the order returned by the filesystem, which is undefined. But order is significant when multiple files define the same configuration key: the "last" one wins.
