Hey all,based on the feedback so far, I revised the PEP. There is now
a much simpler rule for allowed underscores, with no exceptions.
This made the grammar simpler as well.

Examples::# grouping decimal numbers by thousands
amount = 10_000_000.0# grouping hexadecimal addresses by words
addr = 0xDEAD_BEEF# grouping bits into bytes in a binary literal
nybbles, not bytes, is shown... which is more readable, and does
group into bytes also.
flags = 0b_0011_1111_0100_1110
+1 on 0b_ and 0X_ and, especially, 0O_ (but why anyone would use
uppercase base designators is beyond me, as it is definitely less
readable)
# making the literal suffix stand out more
imag = 1.247812376e-15_j
