printf("%u", num) shows pointless ".." for negative num #3400

printf family functions place ".." before the string representation of a negative value for non-decimal format specifiers:

% ruby -e 'printf "%x\n", -1'
..f

% mruby -e 'printf "%x\n", -1'
..f

But, for unsigned decimal format specifier %u, leading ".." is not expected and does not make sense:

% ruby -e 'printf "%u\n", -1'
-1

% mruby -e 'printf "%u\n", -1'
..-1
