But if you don't want the EOLs? Example from some code of mine:

     raise MakeError("extracting '%s' in '%s' did not create the "
                     "directory that the Python build will expect: "
                     "'%s'" % (src_pkg, dst_dir, dst))

I use this kind of thing frequently. Don't know if others consider it 
bad style.
