The adjustment of block length with 'off-by-one' affects content
length during undo operation. The issue occurs when we perform undo
operation for a set of group blocks that have same fragment
position. Since their positions are same, group block change
(QTextDocumentPrivate::documentChange) with respect to insertion
doesn't affect document block length and further adjustment to
'off-by-one' without considering this leads to incorrect document
content change information (such as invalid information with regard
to characters removed).
This patch skips adjustment of group block length during undo
operation.
