Summary: pickle_complex in copy_reg.py

Initial Comment:
This code is in copy_reg.py from 1997:

def pickle_complex(c):
    return complex, (c.real, c.imag)

pickle(type(1j), pickle_complex, complex)

I'm not sure if the function pickle_complex() is
necessary, but it definitely seems that the line after
should be commented out or removed.  pickle_complex()
is not in the doc either.

(I was building WITHOUT_COMPLEX and found this problem.)

I'm rejecting this as invalid. Neal, if you disagree, just
reopen and assign to me.

Without that line you can't pickle complex numbers. Maybe it
should fail gracefully if complex doesn't exist. Feel free
to check in a fix for that.
