[Coco] pacos9 ported to lwtools

[Bill Pierce]

Wayne, in going through litterally hundreds of C and asm sources in the past 2 years, I completely disagree with you.
I see asm sources with the edition byte set to various values all the time, usually reflecting the edition of the program.
In  compiling C or RMA programs, when running the linker you specify -e=xx to set the edition in the compiled program.
You can also set the revision number in asm programs by using the lower 4 bits of the attr byte, usually ReEnt+rev on program files.

The Edition byte in 6809 OS9 is a little different. First, while the
documentation says it is part of the header, it is actually the first byte
after the module name string. This means it is the first byte of the
execution offset address (or the I-Code area address in a Basic09 module).
In either case, it is something that many 6809 OS9 programmers seemed to
get along without and never used.
