#586 Ticket's Markdown preview shows long-line code listing incorrectly

[Nutchanon Wetchasit]

This is a minor issue affecting non-critical functionality.

Few weeks ago, I ran into a problem with SourceForge's ticket system when trying to write a ticket reply with large ASCII art diagram- namely a program code with long lines; Markdown preview area will force-wrap the code, resulting in a mangled diagram preview.

This problem affects only preview on both new-ticket form and ticket reply form; the real posted tickets/comments content are not affected.

Exact steps to reproduce:

• Visit some random SourceForge project's issue tracker.
• Open one random ticket that allows reply, or select "Create Ticket".

• Replying to a ticket (or create a ticket) with following message:

  Following is a large ASCII art diagram:

  End of diagram.
  

• Don't click "Post" (or "Save") yet.

• Click the "Toggle Preview" (eye) icon at the top-right of textarea.
• Preview area will show a jumbled version of ASCII art diagram- which each line wrapped somewhere beyond column 69; see the attached screenshot.
• Now click "Reply", or "Create Ticket".
• You will see that the resulting post shows ASCII art diagram correctly- without wrapping.

Please investigate.
