+		Same as |getregion()|, but returns a list of positions
+		describing the buffer text segments bound by {pos1} and
+		{pos2}.
+		The segments are a pair of positions for every line: >
+			[[{start_pos}, {end_pos}], ...]
+<
+		The position is a |List| with four numbers:
+		    [bufnum, lnum, col, off]
+		"bufnum" is the buffer number.
+		"lnum" and "col" are the position in the buffer.  The first
+		column is 1.
+		The "off" number is zero, unless 'virtualedit' is used.  Then
+		it is the offset in screen columns from the start of the
+		character.  E.g., a position within a <Tab> or after the last
+		character.
