Yup.  Name, arguments, and discoverability all leave something to be
desired.

\augment 2  => shiftDurations #-1 #0
\augment 1/4 => shiftDurations #2 #0
\augment 3/2 => shiftDurations #0 #1 (the second argument is rather
                                      shaky to interpret and use and
                                      only works in limited situations)

Would likely be better discoverable, and more "natural" to use.
