It depends on which "level" of Lisp you are talking about.
On the level which must take the "deep representation" and
show it on the screen, Lisp definitely need to look at 1.,
2., line wrapping, etc.
On the level which navigates "on the screen" in response to
cursor movement, or searching, only looking at the "text" while
ignoring the formatting makes sense. But it will probably have
to be aware of it anyway to DTRT...
I don't think you can have a surface presentation which is
radically different from the deep representation without
writing a suitable set of cursor movement commands to
accomplish it.
Maybe the 'line-move' framework could be extended to allow a specific
surface presentation to mark things to be skipped over (it already
does that in various ways, but maybe there is a way to generalize
that so a minor/major mode can modify the behaviour).
