bors f11502cda8 Auto merge of #26904 - bluss:no-repeat, r=alexcrichton ... In a followup to PR #26849, improve one more location for I/O where we can use `Vec::resize` to ensure better performance when zeroing buffers. Use the `vec![elt; n]` macro everywhere we can in the tree. It replaces `repeat(elt).take(n).collect()` which is more verbose, requires type hints, and right now produces worse code. `vec![]` is preferable for vector initialization. The `vec![]` replacement touches upon one I/O path too, Stdin::read for windows, and that should be a small improvement. r? @alexcrichton		2015-07-09 10:36:41 +00:00
