Subject: [PATCH] (charset_code_point): If CHARSET_CONVERSION is
 CONVERSION_IDENTICAL, identical conversion is used even if
 a CCS is ISO-2022 style; instead of it, CONVERSION_94,
 CONVERSION_96, CONVERSION_94x94, CONVERSION_96x96,
 CONVERSION_94x94x94, CONVERSION_96x96x96,
 CONVERSION_94x94x94x94 and CONVERSION_96x96x96x96 are
 introduced. (complex_vars_of_mule_charset): Specify
 CONVERSION_96 instead of CONVERSION_IDENTICAL for
 thai-tis620; Specify CONVERSION_94x94 instead of
 CONVERSION_IDENTICAL for japanese-jisx0208-1990.
