In 5b-c, is it possible that XDG_RUNTIME_DIR was intended? I can't find any
doc for envar XDG_CONFIG_DIR in the XDG Base Directory Spec (although there 
is an XDG_CONFIG_DIRS, but that seems like that's intended for configuration
stuff rather than for locating runtime files like the socket or pidfile...)

If XDG_CONFIG_DIR was intended (or perhaps just a typo, intended to be ...DIRS) 
then how/where does XDG_RUNTIME_DIR itself come into the picture?
