[docs] zlib.compressobj doesn't accept memlevel argument

[anonyme couard]

when trying to use 
http://docs.python.org/3/library/zlib.html#zlib.compressobj


with the folowwing code

import zlib
page1= b"page1"
page2 = b"page2"
c = 
zlib.compressobj(level=9,zdict=page1,method=zlib.DEFLATED,wbits=15,strategy=zlib.Z_DEFAULT_STRATEGY,memlevel=9)
print(len(c.compress(page2)+c.flush()))

I have the following traceback


Original exception was:
Traceback (most recent call last):
   File "test.py", line 4, in <module>
     c = 
zlib.compressobj(level=9,zdict=page1,method=zlib.DEFLATED,wbits=15,strategy=zlib.Z_DEFAULT_STRATEGY,memlevel=9)
TypeError: 'memlevel' is an invalid keyword argument for this function

I think that memlevel was replaced by wbits at a point and was not 
replaced in the documentation

my suggestion: remove memlevel
