Stripping it down like that leaves a lot of code space unused. I guess the
unused codes should be rejected as I currently do for the default mode.
Maybe I'll include 'extra code space available' in the error message ;-)

One might pass a chunk length integer to str.split, e.g.,

    s.split(n)

to get 

    [s[i:i+n] for i in xrange(0,len(s),n)]

PS. Any other votes on base52?

BTW, this isn't a language thing, so I wouldn't think it's a PEP thing, but
what is the right way to proceed to get it considered for inclusion? A patch
for binascii.c is obvious. Are the following four the whole story? Is the html
automatically generated from the .tex?

D:\Python-2.2.2\Doc\lib\libbinascii.tex
D:\Python-2.2.2\Lib\test\test_binascii.py
D:\Python-2.2.2\Lib\test\output\test_binascii
D:\Python-2.2.2\Modules\binascii.c

D:\Python22\Doc\lib\module-binascii.html
D:\Python22\Lib\test\test_binascii.py
D:\Python22\Lib\test\output\test_binascii

The last two are just duplicates of the source distribution AFAICS.
