[TUHS] Questions about the history of cut(1)

Hoi. What started as the plan to write a short portrait of cut(1) for a free german online magazine (translation to English is not done yet) became a closer look at the history of cut(1). Well, the topic got me hooked at some point. The text is still only about eight pages long and far from scientific quality, but it features some facts not found in Wikipedia. ;-) So, let me come to my questions. 1) The oldest version of cut that I found is this one in System III. http://minnie.tuhs.org/cgi-bin/utree.pl?file=SysIII/usr/src/cmd (The file date says 1980-04-11.) As the sccsid reads version 1.5, there must be older code. How can I find it? Is there a story of how cut appeared for the first time? 2) As far as I found out, POSIX.2-1992 introduced the byte mode (-b) and added multi-byte support for the character mode. Is this correct? 3) Old BSD sources reference POSIX Draft 9 (which, it seems, they implement) but lack multi-byte support and the byte mode. They also support decreasing lists, which, they state, POSIX Draft 9 would not. http://minnie.tuhs.org/cgi-bin/utree.pl?file=4.3BSD-Reno/src/usr.bin/cut/cu… The only POSIX.2 Draft I have access to is Draft 11.2. http://www.nic.funet.fi/pub/doc/posix/p1003.2/d11.2/all.ps It does specify the multi-byte stuff and does also allow decreasing lists. Hence, it appears that these things were added somewhen between Draft 9 and Draft 11.2. Does anyone know details? It would be great, if you can give me some pointers for further research or even share some cut-stories from the good old days. :-) meillo P.S. In case you understand German, feel free to have a look at the current version of the text: http://hg.marmaro.de/docs/cut/file/ I welcome your comments, but bear with me, the text issn't meant to become a doctoral thesis; I just want to write it for fun and to learn about the historical background.
