I'd like to propose the attached patch for problem of invalid LANG
setting.  This simply falls back to "en_US.UTF-8" if LANG isn't valid,
or something valid can't be deduced from the locale.

I find this acceptable even in my setting ("en_DE") because even Apple's
Terminal doesn't get this right.  A closer looks at what is set in the
locale in Terminal shows that, for instance, date format and thousands
separator are en_US anyway.
