Subject: mediawiki.debug: Fix crash in browsers without Function#bind
X-Git-Tag: 1.31.0-rc.0~14257^2
X-Git-Url: https://git.cyclocoop.org/%27.WWW_URL.%27admin/?a=commitdiff_plain;h=5c651dbac8f1e48864a4c6f5658922e7e4e00e9c;p=lhc%2Fweb%2Fwiklou.git

mediawiki.debug: Fix crash in browsers without Function#bind

PhantomJS has a partial ECMAScript 5 implementation but it does
not include Function.prototype.bind.  Detect that and error gracefully
instead of erroring out in the middle of a phantomjs qunit run.
