Dylan Smith 2da0d8e933 richedit: Use ME_Cursor instead of offsets for ME_SetCharFormat.
The test that succeeded from this change was as a result of allowing the
end of the character format change be specified using NULL as the rest
of the text.  Before, the end paragraph run at the end of the text was
not being set for this case, when all the text was supposed to have its
character format changed.
