No. The bug is that if the size of the ring is larger than the
length, the current version of `ring-elements' introduces fake `nil'
elements. The delq gets rid of all nil's, fake ones and potentially
legitimate ones, because certain ring elements could _really_ be nil.
The nconc re-adds the correct number of legitimate nil's. See the
ielm run below.
Ok.
If you want to do a little work, I am sure you could write a single
loop that produces the right elements in the right order. Then you
could rotate it properly with a single call to setcdr followed by
nconc'ing the pieces in the opposite order.
