Replace the ambiguous dash with “to”

Warning²Federal courts, Illinois courts21st and 22nd editions

Where the section numbers in a span carry hyphens of their own, a dash joining them is ambiguous, so the span is written out with the word “to” instead.¹

1. 1R. 3.3(b) Multiple sections and subsections.
2. 2A warning: the form is usually wrong under the rule in note 1, and context can justify it.
