Star 2012.10 behavior

STD behavior

std 04216b1​: OUTPUT«[31m===[0mSORRY![31m===[0mâ�¤Null operator is not allowed at /tmp/0aJaOg4T0V line 1​:â�¤------> [32msub infix​:<>[33mâ��[31m ( ){};[0mâ�¤Other potential difficulties​:â�¤ Pair with <> really means a Nil value, not null string; use :('') to represent the null string,â�¤ orâ�¦

bbkr_ should also complaint about something like "Null operator is not allowed " like STD, right?
* bbkr_ reports
masak yes, it should.

The test in S32-exceptions/misc.t passes and the test file is in 't/spectest.data'.

If the ticket should not be set to resolved (if there is something else to do), please comment.
