build recipe definitions wrap unnecessarily

On the build recipe page (for example: https://code.launchpad.net/~sloecode/+recipe/sloecode-daily), the "recipe contents" section wraps text after approximately 70 characters, which seems much too short. There's nothing to the right on that page.

Further, editing the recipe un-wraps the text, and instead wraps text at the full page width.

Since this is the contents of a bzr-builder recipe, where newlines are part of the document syntax, it's important to make every effort to display recipies correctly.
