hex(-5) => Futurewarning: ugh, can't we have a better hex than '-'[:n<0]+hex(abs(n)) ??

What about crazy people like myself? If you generate a crc32 value with zib,
you occasionally get a negative number returned. If you try to convert that
to hex (to test against a stored CRC32 value), it spits out a FutureWarning
at me. So you end up with silly things like this in your code:
# Disable FutureWarning, since it whinges about us making bad hex values :(
import warnings
try:
warnings.filterwarnings(action='ignore', category=FutureWarning)
except NameError:
del warnings

Remove the oinks!
