Comment 4 for bug 888814

The above elements are not all standard afair, namely kbd, samp, xmp, plaintext and listing. I pondered making some exceptions since many sites grossly disregard semantic markup but that would require site-specific styles as well.

"body" alone needs to be monospaced because raw text files are always displayed like that. See the bugzilla example URL above.

I committed the patch which so far works fairly well for me, except for those non-standard elements.
