& aligns the selections into columns

helix-golf's enumerate_and_align ends on %s |\d+<ret>&. align_selections
treats the k-th range of each line as column k and puts spaces before each
range until its head reaches the widest head of its column, measured in
display cells, which File.rawDisplayCol already gives. A range over several
lines refuses, as in helix. The example itself still needs more than 64
ranges, which the selection model does not hold.
