+ For the particular case of a boundary within a text node containing line breaks (within a <pre> element,

+
+ - 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 method 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.
