Subject: assert: test `RegExp`'s properties when checking for equality
X-Git-Tag: v0.7.0~89
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5c7532e5b3fad40a50696e43fc2ff066af7037c3;p=platform%2Fupstream%2Fnodejs.git

assert: test `RegExp`'s properties when checking for equality

Previous code ignored the fact that `/a/ != /a/g`.

Test case included.
