M-q on comments in source code

[lee]

Hi,

modes like c-mode indent comments with the code, which is fine as an end
result and not so ideal when writing them.  To give an example:


,----
|                       if(full)
|                               {
|                                       //
|                                       // A max value might be removed when 
the arrays are shifted.  In
|                                       // that case, find a new one after 
shifting.  Otherwise, the max
`----


Now press M-q to format the comment and the above looks like this:


,----
|                       if(full)
|                               {
|                                       //
|                                       // A max value might be
|                                       // removed when the arrays are
|                                       // shifted.  In that case,
|                                       // find a new one after
|                                       // shifting.  Otherwise, the
|                                       // max continues to be known.
`----


This formatting is a bit silly ...  What can I do to get the comments
formatted as in the first example, i. e. the comment indented with the
source but with each line trimmed to a length of about max 75
characters, not counting the indentation?

I can manually unindent the lines, edit them, format them and reindent
them, and I`m looking for a better way.  Even something like
auto-fill-mode for comments that does it automatically would be nice.
