-                        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.
