Summary: Allow leading 0 in float/imag literals

Initial Comment:
Many years ago I was baffled that "0e0" as a literal 
gave an error (it doesn't as a string argument to 
float), and I never got used to it.  While fixing a 
bug earlier today, I noticed this comment in 
tokenizer.c:

/* XXX This is broken!  E.g.,
   09.9 should be accepted as float! */

09.9 is accepted after the patch, but along with stuff 
that isn't so clear, like 0777j same as 777j.  OTOH, 
even at that extreme, complex("0777j") returns 777j 
without this patch too.
