Returns an [Array] of line ranges where [code]x[/code] is the first line and [code]y[/code] is the last line. All lines within these ranges will have a caret on them or be part of a selection. Each line will only be part of one line range, even if it has multiple carets on it.
If a selection's end column ([method get_selection_to_column]) is at column [code]0[/code], that line will not be included. If a selection begins on the line after another selection ends and [param p_merge_adjacent] is [code]true[/code], or they begin and end on the same line, one line range will include both selections.
