+a pure property.  The pure property is evaluated (and cached) for all
+pure calculations, and the unpure is evaluated for all unpure calculations.
+In this regtest, there are three groups of two eighth notes.  In the first
+group, the second note should move to accommodate the flag, whereas it should
+not in the second group because it registers the flag as being higher. The
+flag, however, remains at the Y-offset dictated by ly:flag::calc-y-offset.
+In the third set of two 8th notes, the flag should be pushed up to a Y-offset
+of 8.
