That usage of LANG is new to me... I wonder how well the
multiple options settings fit the current API.

Would you be willing to supply a patch to locale.py which
adds multiple LANG options to the interface ?

I guess we'd need a new API getdefaultlocales() [note the trailing
"s"] which will then return a list of locale tuples rather than
a single one. The standard getdefaultlocale() should then return
whatever is considered to be the standard locale when using the
multiple locale notation for LANG.
