Unfortunately there isn't, AFAIK, an option to rotate without enlarge; the
only solution I have found is to rotate then crop.  Using the built-in
rotate, and then 'manually' (ie in a transcript function) cropping, is still
much quicker than writing your own rorate code (at least, with my attempt!).
Depending on your needs, you can write your own crop routine now (remember -
using 'repeat for each', although more clumsy, is _much_ faster than 'repeat
with'); or wait for Rev 2.0 which has a crop command built in.
