* nlsfuncs.cc (lc_wcstombs): Add `return_invalid' flag to specify 

whether invalid chars should be ignored or not.  Change comment.
	(__set_lc_monetary_from_win): Call lc_wcstombs with return_invalid
	flag set.
	(__set_lc_messages_from_win): Simplify to accommodate the fact that
	lc_wcstombs just ignores invalid chars.  Explain why.
