A line-shape function is a frequency-density distribution. It's a collection of frequency-lines (like this one: 7:52), each with its own HEIGHT and WIDTH. It is this width that Mr Heisenberg was talking about. This means that the distribution isn't perfectly continuous.

Excellent presentation of very important material. Can you say anything more about the effects of absorption and emission on the lineshape function?
