pad repo files with 0 bytes, not random memory

so you can do:
./razor import-yum
mv rawhide.repo rawhide.repo.orig
make
./razor import-yum
diff rawhide.repo.orig rawhide.repo

(doesn't work with system.repo at the moment...)

 .gitignore

 *.o

 *~

 *.repo

 razor

 test-driver

 pkgs

 set

 primary.xml.gz

 filelists.xml.gz
