if the "Region equivalents overlap" (badly named) option is enabled,
then the test of whether a region in track B is "equivalent" to a
selected region in track A simply comes down "does it overlap with the
selected region" ?

if the option is not enabled, then for regions to be considered
equivalent, their start point in their source file(s), their position
on the timeline and their length must be exactly equal to the selected
region.
