[I have extended it to two lines for what I hope is better clarity.]

But Bart's condition begins with (), and I am having the darndest time discovering what
this means.

without the () the line would be <$(ws)

which means "if the size of the message is less than $(ws)

the () acts as an escape on the < and is stylistically preferred to \< when at the beginning of a pattern, although I believe the effect is the same.
