     element, for example), we need a slightly complicated approach to get the boundary's offset in
+                        IE. The facts:
+                        
+                        - Each line break is represented as \r in the text node's data/nodeValue properties
+                        - Each line break is represented as \r\n in the TextRange's 'text' property
+                        - The 'text' property of the TextRange does not contain trailing line breaks
+                        
+                        To get round the problem presented by the final fact above, we can use the fact that TextRange's
+                        moveStart() and moveEnd() methods return the actual number of characters moved, which is not
+                        necessarily the same as the number of characters it was instructed to move. The simplest approach is
+                        to use this to store the characters moved when moving both the start and end of the range to the
+                        start of the document body and subtracting the start offset from the end offset (the
+                        "move-negative-gazillion" method). However, this is extremely slow when the document is large and
+                        the range is near the end of it. Clearly doing the mirror image (i.e. moving the range boundaries to
+                        the end of the document) has the same problem.
+                        
+                        Another approach that works is to use moveStart() to move the start boundary of the range up to the
+                        end boundary one character at a time and incrementing a counter with the value returned by the
+                        moveStart() call. However, the check for whether the start boundary has reached the end boundary is
+                        expensive, so this method is slow (although unlike "move-negative-gazillion" is largely unaffected
+                        by the location of the range within the document).
+                        
+                        The approach used below is a hybrid of the two methods above. It uses the fact that a string
+                        containing the TextRange's 'text' property with each \r\n converted to a single \r character cannot
+                        be longer than the text of the TextRange, so the start of the range is moved that length initially
+                        and then a character at a time to make up for any trailing line breaks not contained in the 'text'
+                        property. This has good performance in most situations compared to the previous two methods.
