According to cat.s, fd 8 is standard error (not fd2!). I've updated
...
the a7out simulator to have STDERR on fd 8.

017777, oops. I've added more comments to wktcat.s (renamed from
simplecat.s). Now we need to find out how the real PDP-7 Unix
does command line arguments.

I've added tad and sza to the a7out simulator, and I also added some
...
code to place command-line arguments into the simulated memory. I'm
trying to write my own version of cat so I can compare mine to the
real one. Right now there's a bug when simplecat has two arguments.
Zero and one arguments are OK! Saving so I have a backup before proceeding.

I've changed the assembler so that it groks the <ab> string literal
...
syntax. I think it's OK, but it probably needs more testing.
write_test.s was changed to exercise the string parsing.

Ken Thompson sent e-mail in to explain that there can be labels mid-line, such as
...
sys write; 1:0; 4
so I modified the assembler logic to support this, and added some code to write_test.s
to verify that it works.
