The offset map was broken from the start because it wasn't updated when
adjusting the length of a text node, and if we fix that bug it's
doubtful whether the costs of updating the offset map outweigh the
benefits, especially considering that adjusting the length of a text
node is something we do for almost every keypress. If it turns out
having an offset map does make sense, we can always reintroduce it
later.

This was because the while loop was never entered as end >= left was
true from the start. Convert the while loop to a do-while loop to make
sure it runs at least once

This is for the case where we have a zero-length range in between two
siblings, and we need to know what index that corresponds to in order to
be able to insert nodes there (rebuildNodes() will use it for this
purpose)

* Initialize startOffset to 0 not 1, don't know what I was thinking
* Use currentFrame for nodeRange instead of parentFrame, don't know what
I was thinking there either
* If the returned node has no parent (is the document node), don't
attempt to access parentFrame and don't set index

Selecting a zero-length range at the start or end of a text node
(e.g. (1,1)) would return the text node's parent instead of the text
node

* Needs to be initialized to 1, not 0
* Needs to be stored *after* left is incremented to account for an
opening
