By my reading of CLtL2, "~:@<return>"  would be identically equal to just
including the <return> in your format string, i.e. it includes the return
and the whitespace characters which follow it.  "~<return>" includes
neither , "~:<return>" includes just the whitespace, and "~@<return>"
includes just the newline, so you have all four combinations.
