    newvers.sh: Avoid picking up stray envars.
    
    89f361f742ae added a mechanism to allow arbitrary overrides from the
    command line.  Unfortunately, it also had the (likely unintended)
    effect of allowing RELEASE and VERSION to be passed in from the
    environment, and Makefile.inc1 happens to define VERSION for the
    benefit of pkgbase.  To restore the status quo, unset RELEASE and
    VERSION at the top of the script.
