A new line in the comment text seems to cause non-match

[efip-ns]

Jenkins and plugins versions report

Environment

Same as #91 

What Operating System are you using (both controller, and any agents involved in the problem)?

Linux

Reproduction steps

1. Step 1: define the triggering comment as \\[ci-merge\\]
2. Step 2: issue a comment of [ci-merge]\r\n (a new line in the end).

Expected Results

I'd expect the comment to trigger the build, as it says in the documentation:

Regular expression matching

The regex is not surrounded with any markers and uses the Pattern.CASE_INSENSITIVE and Pattern.DOTALL Java flags.

Actual Results

The build is not triggered.

Anything else?

The build is triggered after I edit the comment and remove the new line.

Are you interested in contributing a fix?
