* Revised locale initialization to interpret
environment variable locale values according to XPG4, and to recognize the LC_ALL and LC_MESSAGES values over that of LANG. Also added many Windows Registry locale values to those recognized by msgcat. Revised tests and docs. Bumped to version 1.3. Thanks to Bruno Haible for the report and assistance crafting the solution. [Bug 525522, 525525]
