emitter: current substitution can be multi-line In `splice_lines`, there is some arithmetic to compute the required alignment such that future substitutions in a suggestion are aligned correctly. However, this assumed that the current substitution's span was only on a single line. In circumstances where this was not true, it could result in a arithmetic overflow when the substitution's end column was less than the substitution's start column.
