Hi, I have run into a problem with the program_options library chopping words when it formats help messages. I have created a small code fragment that will duplicate the problem: int main() { std::string p = "\n1234 6789 1234 6789 1234 6789 1234"; format_description(std::cout, p, 20, 44); return 0; } Results in this message: 1234 6789 1234 6789 123 4 6789 1234 In case formatting is not preserved, the 3'rd instance of '1234' is chopped into '123' with '4' on the next line. I think there might be a bug in format_paragraph in the block that is supposed to prevent word chopping. Specifically, this piece of code: // is last_space within the second half ot the // current line if ((unsigned)distance(last_space, line_end) < (line_length - indent) / 2) { line_end = last_space; } should probably not subtract 'indent' from 'line_length' since this was already done at the very beginning of the function. Thanks, Soren Soe.
