The old test
x if ((len(repr(chr(x))) == 3) and (x < 127)) else ord('.')
went through some contortions to see if the character was printable, and
it got it slightly wrong. The idea was that `repr(chr(97)` is "'a'",
while `repr(chr(167)` is "'\xa7'", which we can distinguish using the
length. But that miscategorised the backslash character, which is
represented as "'\\'", a string of length 4, so it was show as '.'
instead.
Instead we notice that the characters we want to print in a hexdump
are exactly those between 32 and 126, inclusive.
