Included patches make some enhancements to the multi-byte support.
o allow to use Big5 (a Chinese encoding used in Taiwan) as a client encoding. In this case the server side encoding should be EUC_TW o add EUC_TW and Big5 test cases to the regression and the mb test (contributed by Jonah Kuo) o fix mistake in include/mb/pg_wchar.h. An encoding id for EUC_TW was not correct (was 3 and now is 4) o update documents (doc/README.mb and README.mb.jp) o update psql helpfile (bin/psql/psqlHelp.h) -- Tatsuo Ishii t-ishii@sra.co.jp

* Add regression test case for EUC_TW
