Under some circumstances it's possible to get a divider 0 which crashes
the script.
Traceback (most recent call last):
File "linux/scripts/bloat-o-meter", line 98, in <module>
print_result("Function", "tTdDbBrR", 2)
File "linux/scripts/bloat-o-meter", line 87, in print_result
(otot, ntot, (ntot - otot)*100.0/otot))
ZeroDivisionError: float division by zero
Hide this by checking the divider first.
