Small cleanups to the REP scripts. (#396)

1.  Removes instances of /usr/bin/env python, which don't
    work on non-Linux and also were wrong in some cases.
2.  Makes sure to use raw strings for regexes, which gets
    rid of some warnings with modern Python.
3.  Uses '-f' when removing files to quite warnings.
