Summary: Previously, i18n are initialized at module import time, and cannot be reinitialized if HGPLAIN is changed. That makes chg server has to hash HGPLAIN, and use different servers if HGPLAIN is set. Change i18n to be only initialized at `dispatch._dispatch` time, after chg server updating environment variables. So a same chg server could serve different languages or encodings.
