No, <= 67 chars, not 75 chars.

This is especially important for resizing of windows or frames to fit their
widest line.


>From (elisp) Documentation Tips:

  Format the documentation string so that it fits in an Emacs window
  on an 80-column screen.  It is a good idea for most lines to be no
  wider than 60 characters.  The first line should not be wider than
  67 characters or it will look bad in the output of `apropos'.
