Re: more problems with line-move

[Stefan Monnier]

I don't have time to look into this code right now, but it seems that
line-move sometimes gets stuck.  If all the primitives (including goto-char
in the presence of intangible) guarantee that point always moves in the
intended direction, it shouln't be too difficult to make sure that
line-move never gets stuck.

I tried to do that with my `invisible' patch: it *can* happen that
one command appears not to do anything but it should never get stuck
indefinitely if you repeat it: point might be moved from one part of the
invisible text to another, but if the command moved point, my code tries to
make sure it does not undo the move, so repeating the command should
eventually lead to a visible change of position.
