Subject: [PATCH] Ticket #2210: adjust locale setup fallback to try more
locales on the system if en_US isn't available. We just need *something*
other than C or POSIX to let gettext initialize itself, apparently... Gets
Spanish, French, Russian etc UI localization working on Debian Lenny fresh
installation set up in Spanish (so es_ES.UTF-8 is available but en_US.UTF-8
isn't).
