Link text in API docs is reversed in Internet Explorer

[osobolev]

CSS style "pre.rust" declares scaleX(-1), which reverses text in Internet Explorer.

[huonw]

It actually declares pre.rust a, and is designed to reverse text, to flip the arrow in the "run on playpen" link:

(Of course, doing it in a less hacky manner is good.)

[tinaun]

the arrow has its own css class .test-arrow. the transform should be defined there, not over a more general selector

in addition, transform: scaleX() doesn't work in chrome, needs to be -webkit-transform
