[pdp7-unix] pdp7-unix master branch now using original commands; as tweak

I just pulled a cleaner set of commits for integrating the original
commands, this time keeping "alt" builds (tho possibly with some of
the original commands that expect .. and dd as opposed to . and ..  of
the alternate universe).

I also just pushed a as7 change that makes it OK to redefine a global
label (outputs a warning) and adds a --no-labels-warning flag to
suppress the warning.

space travel still gets an error:

    phil at p27:~/pdp7-unix/scans$ ../tools/as7 --no-label-warnings st?.s fop.s 
    I
    Illegal octal digit '8' ignored at ../tools/as7 line 517, <$IN> line 44.

from this:
    phil at p27:~/pdp7-unix/scans$ grep 028 st?.s
    st7.s:crash: -028;0200000;0

The original as doesn't complain:
