LANG, LC_ALL... in fdo and wm.jl

[Teika Kazura]

Hi. It's on i18n (=internationalization) in fdo-menu.jl and wm.jl.

* lisp/sawfish/wm.jl checks language as:
  (let ((lang 
           (or (getenv "LANGUAGE") (getenv "LC_ALL")
               (getenv "LC_MESSAGES") (getenv "LANG")))
but is this the correct order? I think LC_ALL should the last, but
don't know others.

* fdo-menu.jl only checks LANG, but it should check above 4, right?
