	(java_unicode_2_utf8): Fixed utf8 encoding in the 0x800-0xffff
 	range.
	* parse.y (valid_builtin_assignconv_identity_widening_p): Fixed
 	comments. Local variable `all_primitive' is gone. Broadened
 	acceptance of `0' to floating point targets. `long' can now be
 	widened to `double' or `float'.

 	comment. Fixed tabulation.
	(build_string_concatenation): Optimize out left or right empty
 	string constants.
