Currently there is a bug whereby if a new patch introduces more than one new dependency (or removes more than one) it breaks the Github post output (see [this build](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/29399/consoleFull)). This hotfix will remove `awk` print statements in place of `printf` so as not to automatically add the newline character which is then escaped and added directly at the end of the `awk` statement. This should take a failed build output such as:
```json
data: {"body": " [Test build #29400 has finished](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/29400/consoleFull) for PR 5266 at commit [`2aa4be0`](2aa4be0e1d).\n * This patch **passes all tests**.\n * This patch merges cleanly.\n * This patch adds the following public classes _(experimental)_:\n * `class IDF extends Estimator[IDFModel] with IDFParams `\n * `class Normalizer extends UnaryTransformer[Vector, Vector, Normalizer] `\n\n * This patch **adds the following new dependencies:**\n * `avro-1.7.7.jar`
* `breeze-macros_2.10-0.11.2.jar`
* `breeze_2.10-0.11.2.jar`\n * This patch **removes the following dependencies:**\n * `avro-1.7.6.jar`
* `breeze-macros_2.10-0.11.1.jar`
* `breeze_2.10-0.11.1.jar`"}
```
and turn it into:
```json
data: {"body": " [Test build #29400 has finished](https://amplab.cs.berkeley.edu/jenkins/job/SparkPullRequestBuilder/29400/consoleFull) for PR 5266 at commit [`2aa4be0`](2aa4be0e1d).\n * This patch **passes all tests**.\n * This patch merges cleanly.\n * This patch adds the following public classes _(experimental)_:\n * `class IDF extends Estimator[IDFModel] with IDFParams `\n * `class Normalizer extends UnaryTransformer[Vector, Vector, Normalizer] `\n\n * This patch **adds the following new dependencies:**\n * `avro-1.7.7.jar`\n * `breeze-macros_2.10-0.11.2.jar`\n * `breeze_2.10-0.11.2.jar`\n * This patch **removes the following dependencies:**\n * `avro-1.7.6.jar`\n * `breeze-macros_2.10-0.11.1.jar`\n * `breeze_2.10-0.11.1.jar`"}
```
I've tested this locally and all worked.
