I've just gone through `comment-dwim' in edebug (the Emacs debugger), and
it seems like comments are being made to fit within `fill-column'.  I
don't know why this is being done, but could you try setting it to a high
value, say

    (setq fill-column 150)

.  Does this solve the immediate problem?  Does it introduce any new
problems?
