QTextStream::operator<< calls QTextStreamPrivate::putString, which was
taking a copy of the user's string and modifying it depending on
padding. That is not necessary, since we're only talking about
padding. Instead, calculate the left and right paddings. For the case of
"accounting padding", we move the sign (if any) to the beginning of the
left padding and skip it in the data.
The one side-effect I can think of is that the stream could flush in the
middle of the writing operation.
The debugging section had to be removed because it doesn't make sense
anymore.
