Comment 0 for bug 262718

Bug descriptions and comments use the fmt:text-to-html formatter to convert them into <p> and <div> elements, and (via id="bug-description" and class="bug-comment") special CSS to convert them to monspace.

Meanwhile merge proposal comments use <pre style="white-space: pre-wrap;">, which produces a single line of text per paragraph -- regardless of the length of the paragraph -- in browsers like Firefox 2, Internet Explorer 7 and Safari 2.0.

These should be made more consistent and cross-browser. Either:
* merge proposal comments should use fmt:text-to-html like bug descriptions and comments do, and all three should use a class= to achieve a monospace font; or
* bug descriptions, bug comments, and merge proposal comments should all use <pre>, and <pre> should be styled using {white-space: pre-wrap} as well as browser-specific properties like word-break so that it wraps in as many browsers as possible.
