Increase the minimal node width of each selected node by a "step" amount.
If more than one node is selected, the minimum with for each node is set
to the minimum width of the larger one (after increment).
Ensure that the new minimal width is a multiple of the step.

Based on zipizap script for same purpose,
and nnako "toggle block view for all siblings" script.
