But if we are going to set\none, the important one is LC_ALL. It overrides specific LC_* variables,\nwhich in turn override LANG.

I suspect that the habit dates back to before LC_* was widespread\nand some platforms needed LANG. On modern systems that understand i18n\nand do not need to set NO_GETTEXT, forcing LC_ALL should be sufficient.\n\n> Other than that, the patch is obviously the right thing to be doing.
