New issue 1813 by utatane.tea: String new RegExp('\n').toString() returns
is invalid RegularExpressionLiteral
http://code.google.com/p/v8/issues/detail?id=1813
new RegExp('\n').toString() returns
/
/
, so this result is including LineTerminator.
And, according to ECMA262 section 15.10.6.4
"The returned String has the form of a RegularExpressionLiteral that
evaluates to another RegExp object with the same behaviour as this object."
http://es5.github.com/#x15.10.6.4
And, because of RegularExpressionNonTerminator, LineTerminator is not
allowed in RegularExpressionLiteral. So RegExp.source should be escaped.
Furthermore, new RegExp('\\\n').toString() should provide /\n/, because
/\\\n/ doesn't have the same behaviour to new RegExp('\\\n').
I also reported it to WebKit JSC
https://bugs.webkit.org/show_bug.cgi?id=71572, and created patch for V8.
This patch solves issue 956 at the same time.
