Re: line-move-visual never set to nil?

[Richard M Stallman]

    Wouldn't it be more correct to say that the requirement is that during 
    execution of the macro the command should do the same thing to the 
    buffer as during recording of the macro?

In some sense yes, but when the command's behavior is conditional on
something (whether it be buffer text, or how text appears on the
screen), it has to be conditional in the macro just as it is
conditional when you run the command from the keyboard.

The only way to get rid of these commands' dependence on the window
width is to make the line breaking not depend on the window width.
That might be a good idea.  If some other parameter controls where to
do the line-breaking at word boundaries, rather than the window width
directly, you could set that parameter differently in order to run the
macro.
