I don't understand how it would be useful in the pprint module if it
can't be useful as a general function. The general intent is the same:
print something in a "nice" way. Just the nice way is different
depending on the situations: if my bytes object is simply a bunch of
HTTP headers, I don't want to have a hexdump.

This won't work very nicely in smaller display widths. You'll need too
many lines to represent a bytes object.
