prevent out of bounds string access
Yet another reminiscence of String to OUString conversion..
where the terminating NULL-character was obtained and
SvNumberformat::InsertBlanks() effectively did nothing.
Could be triggered already by entering an '_' underscore character as
number format code, which is a place holder for blanks of the same width
as the following character, which there isn't then yet.
