When rewriting large amounts of ASCII text (or comments in Code), I really find "par" helpful.

    : Just use it in :
    : vi with your cursor in front of a badly wrapped block of text. :
    : Press !}par<enter> and the text will be :
    : piped to par :
    : which fixes up :
    : the :
    : formatting and keeps aligned frame markers :
    : intact magically. :

Or you can just select the block of text and type gq. This will do what par does, and can be adjusted with vim's 'textwidth' and 'formatoptions' settings.
