#this script called from /usr/sbin/quicksetup, /usr/bin/wmreboot, wmpoweroff.
#passed in params: $NEWLANG
#120401 change logic to modify init (see also quicksetup).
#121124 ensure that all [ ] are escaped in initrd translation-file. see also /usr/sbin/fixdesk, fixmenus.
#121125 revert 121124.
#121126 restore 121124, plus escape '.' chars in regex.
