One major weakness of the current usage of 
INSTALLED_FILES in bdist_rpm leaves directories 
unlisted thereby causing an uninstall of a package to 
leave these behind.  This patch separates out into 
another option --record-rpm and function that generates 
a list friendly for RPM consumption. 
 
It currently handles data_dirs and install_lib (everything 
under site-packages).  In addition, languages found 
under the common LC_MESSAGES sub-directory is also 
automatically tagged with %lang(de) attribute. 
Documentation does not need to be handled since RPM 
already sets this up if the packager uses %doc. 
 
I've run a couple of tests with this patch showing good 
results. Before taking the concept further, I submit it 
here for your review.
