comment-padrightcomment-padright is a compiled Lisp function in `
newcomment.el'. (comment-padright STR &optional N) Construct a string composed of STR plus `comment-padding'. It also adds N copies of the last non-whitespace chars of STR. If STR already contains padding, the corresponding amount is ignored from `comment-padding'. N defaults to 0. If N is `re', a regexp is returned instead, that would match the string for any N.
