I guess it's a bug. The code in rept_irpc.c line 44 seems to decrement
and check the count only at the end of producing the body of the REPT
block. That is easily fixed. Several of the regression tests pick up a
change now and I think it looks correct.

I am listing the repeat count as a computed value. I'm not sure if the
original MACRO11 did this but it seems practical.

I started working on this assembler a couple of years ago when I
suddenly felt the overly optimistic need to incorporate the latest
changes from KERMIT-11 into the RSX11-M+ version of Kermit. An assembler
on a bigger system would be a nice help, but the one I found was more
RT11-like, and not the latest version either. So I debugged it a bit and
changed it where it deviated too mich from
AA-KX10A-TC_PDP-11_MACRO-11_Reference_Manual_May88.pdf. If you find
anything else that seems to deviate from either expectations or that
reference, please let me know.
