Line breaks in commit messages

In Go 12.2.2, the revision comments on a build's Overview and Materials pages do not keep line breaks from commit messages - it just clumps all lines together, as you can see in the attached screenshot. This doesn't support the common style (e.g. in Git) of having a summary on the first line and more details on the following lines. This should be fixable by replacing "\n" with "<br>" in the comments.
