show() is broken in 1.1 (on Unix, at least).  The _dump method
in Image.py contains a check for "format == PPM"; it should check
for None or PPM.

save() is broken for TIFF files only under 1.6 and 2.0.  To fix this,
add extra parenthesis around the arguments to the three append
calls around line 325 in TiffImagePlugin.py.

We plan to release a new version before the end of this month;
