I have discovered the cause of the confusions about the
`cs' scroll region command.
Emacs has been handling %i incorrectly. Its documentation
%i increment by one, no output
did not tell me it should increment two arguments.
Cursor motion was handled by old code I got from chris@maryland
so it worked correctly.
I designed the arguments to the `cs' string to make the
VT100 termcap entry do the correct thing with %i working wrong.
The fix to this is:
In tparam.c, in function tparam, add the line
argp[1] ++;
just after the line
case 'i':
In term.c, in set_scroll_region, change the line
tparam (TS_set_scroll_region, buf, start, stop);
to
tparam (TS_set_scroll_region, buf, start, stop - 1);
