comment notification missing old line break

[askamanager]

Before the last Wordpress update, when comment notification emails were sent, they were formatted like this:

Comment:
Text of comment here

Now they're formatted like this:
Comment: Text of comment here

In other words, it's missing the line break it used to have between these two lines. It now reads like each comment starts with the words "comment." It was much easier to scan the comment text before (when it started on a new line).
