      <p>
        <div>
        <pre>It seems that real offset is used to update delta instead of original offset
(RewriterBuffer::RemoveText()):

if (posI != end() && *posI == '\n') {
  Buffer.erase(curLineStartOffs, lineSize + 1/* + '\n'*/);
  AddReplaceDelta(curLineStartOffs, -(lineSize + 1/* + '\n'*/));
}

Is it correct that the same offset is used in Buffer.erase() and
AddReplaceDelta()?</pre>
