Argh... my line by line fix list got munged. You'll have to apply imaginary comments to delimit each fix. 

The bug this fixes is 124981 "zlib decompress of sync-flushed data fails"

A lot of the patch changes are simply whitespace changes to clean up the formating. The patch can probably be edited to only include the changes to the PyZlib_objdecompress routine to fix the most important bug, but this would leave the code even more inconsistant than it is. Most of the rest of the fixes are to make the other routines cleaner, though they do also fix the minor bugs mentioned.
