/**
* Migrates buses using legacy multi-label joining behavior.
*
* In KiCad versions before 6.0, you were allowed to place multiple labels
* on a given bus subgraph, and that would have the effect of making those
* bus descriptions equivalent according to the bus vector number.
*
* For example, if the labels PCA[0..15], ADR[0.7], and BUS[5..10] are all
* attached to the same subgraph, the intention is that there is connectivity
* between PCA0 and ADR0, between PCA10 and BUS10, and between PCA5, ADR5,
* and BUS5 (basically connect all the prefix names where the vector numbers
* line up).
*
* This is no longer allowed, because it doesn't map well onto the new
* bus groups feature and because it is confusing (the netlist will take on
* one of the possible names and it's impossible to control which one is
* used).
*
* This dialog identifies all of the subgraphs that have this behavior,
* and corrects them by determining a new name for the subgraph and removing
* all but one label. The name is determined by choosing a prefix and bus
* vector notation that can capture all the attached buses. In the above
* example, the result would need to have the vector notation [0..15] to
* capture all of the attached buses, and the name could be any of PCA, ADR,
* or BUS. We present a dialog to the user for them to select which name
* they want to use.
