// RULE: A variable cc can copied wherever.
// If its repeat ancestors change, its "vary in repeat"
// will need to change (to lowest common denominator).
// If this cc is not in any repeat,
// make the answer top level and we're done
// Otherwise, could assume its position is OK wrt
// existing repeats.
// So if anything, we just need to move it
// up the tree until
// we reach a node which contains this additional repeat.
// But we'd like this code to
// be used for both moves and copy. (Move case
// needs this constraint relaxed)
// So our algorithm finds viable positions
// (ie ancestors common to all
// repeats).
// That node and higher are candidates for new position
// Ask user to choose.
