• wrap_maybrk(A)

  • A is input string, assuming 80-width limit and no prepending or appending.

• wrap_maybrk(A,B)

  • A is input string, B is width limit, assuming no prepending or appending.

• wrap_maybrk(A,B,C)

  • A is input string, B is width limit, C is prepended string, assuming no appending.

• wrap_maybrk(A,B,C,D)

  • A is input string, B is width limit, C is prepended string, D is appended string.
