Because I think that the "\n" is mainly used for splitting paragraph,
so the auto wrap is still useful when there is a "\n", e.g.:

DESCRIPTION = "FOO \n<Too many characters>"

The ouput is:
  FOO
  <74 characters>
  <74 characters>
  [snip]

I think that this is better than:
  FOO
  <Too many characters>
