I'll implement this for Decimal;  it shouldn't take long.

One question from the PEP, which I've been too slow to read until
this morning:  should commas appear in the zero-filled part of a
number?  That is, should format(1234, "09,d") give '00001,234'
or '0,001,234'?  The PEP specifies that format(1234, "08,d")
should give '0001,234', but that's something of a special case:
',001,234' isn't really a viable alternative.
