Following the recent Bugzilla upgrade, sometimes when you click "reply" in Bugzilla, it inserts the text into the text area with quote markers (">") as expected, but it sometimes wraps the lines strangely (with one or two words on their own line inexplicably). I'm not sure why. I guess there were changes to Bugzilla's comments.js or something?
You can see an example of the strange line wrapping at bug 42734 comment 4.
