fix: Avoid sometimes too wide percent figure in --show-stats

If the nominator is 99999 and the denominator is 100000, the percent
function in Statistics.cpp would return "(100.00%)" instead of the
wanted "(100.0%)". Fix this by using the alternate format string if the
result string overflows its target size.
