The remaining cases of packages which have a dependency on python and/or 
python2 are either this (packages which contain a python script with a 
python shebang line), or the other case which I hadn't previously 
considered - a package which contain an executable or shared library 
linked with libpython2.7.dll.

So, again I need inspect these to determine what should happen to them.
