This is needed to make Mercurial read the HGEXTENSIONPATH to detect
third-party extensions. It is called HGEXTENSIONPATH and not
HG_EXTENSION_PATH to keep it consistent with other environment variables for
Mercurial, e.g. HGENCODINGAMBIGUOUS, HGEDITOR ... Hopefully I or someone else
will get this into Mercurial proper.
