bug_email.pl does not wrap the long description taken from the message body. The future solution to bugzillas general wrapping problem (bug 11901) could be used here also.

ok, after thinking about this, the direction we're heading is to store it in the database as entered (whether there's linebreaks or not) and do the word-wrapping at display time. Currently Bugzilla doesn't do any wrapping at all, it depends on the entering user's browser. Closing this WONTFIX because the solution on bug 11901 will fix this at display time without us having to touch bug_email at all.
