[Coco] wrong helpmsg file

[Bob Devries]

Hi all,

While "playing"with Bill's starter kit, I noticed that the wrong 
"helpmsg" file is in the SYS directory.

The file that is in there seems to be the helpmsg file from multiview, 
which is by far not a complete helpmsg file.

The file nitros9/level2/coco3/sys/helpmsg in the repository is the 
correct one. I haven't yet checked the other files (deluxe, atari,...)

Just a heads-up for the repository maintainers.
