Uh, oh. It seems that I have to revert or modify the change. Anyway,
it looks strange to me that
right;
line from 1,1 then up 1
(which is, according to your tests with AT&T pic, the same as `line 0
from 1,1 then up 1') should be have in a different way compared to
right;
line then up 1;
(which is the same as `line right then up 1').
Am I doing something wrong? Opinions?
