Main bug display page problems - comment content and formatting

The page produced by LP when I try to look at the conversation in a
bug report mangles the commenters' formatting and fails to provide
important information about the bug history.

1. Comment text should be displayed in a fixed width font.

2. Comment text should be wrapped, if at all, only so as to fit in the
   browser window (ie, only as necessary to avoid horizontal
   scrolling). Any wrapping should be visibly marked so that it is
   possible to tell, by looking at the screen, where the actual line
   boundaries are. (Wordwrap is not necessary but not harmful
   provided the above conditions are met.) See my other bug about
   page layout.

   It is possible that the structure of LP's comment entry system
   encourages the submission of comments with paragaphs all run
   together into a single line, in which case wordwrap would be
   essential. It's difficult to tell by looking at the current
   displays.

3. Status changes and comments should be interleaved in the bug
   history, and displayed in chronological order; when a single user
   action does several things (eg, adds a comment and changes the
   status, and/or changes several things at once), the display should
   show one action but also appropriately highlight the status
   changes. Ie, status changes should use formatting which visually
   distinguishes them from running comment text (both for ease of
   noticing, and for ease of ignoring). See the Debian BTS for
   an example of one way to do this.

4. GPG signatures, extensive mail headers, and other usually
   irrelevant information, should be relegated to a subsidiary
   `detailed history' or `uninteresting guff' page. In general, all
   metadata such as incoming email headers will either (a) be normally
   interesting and should therefore be presented in a structed manner
   in the LP page layout proper or (b) be normally uninteresting and
   should therefore be suppressed in the usual view.

5. The full headers and text of incoming emails should be available on
   request. As a pair of litmus tests, the full detailed view should
   be useable (a) to reverify the GPG signature on an incoming mail
   and also (b) to help diagnose mail routing problems and delays by
   detailed analysis of headers such as Received chains.

6. The repetition of the bug title at the top of each comments is
   superfluous. Furthermore, it serves to distract the eye from the
   fact that the grey box does contain some often-useful information
   such as the author and date of a comment.
