Hmm... that's a standard problem that I've seen as far back as from my
Clipper days, and there's a relatively simple standard solution: make
changes in settings undoable.
E.g. have a new directive (:revertlinebreaks:), which will restore the
line break settings as they were before the last (:linebreaks:) resp.
Internally, you'd have to keep a stack of linebreak states, but I hope
you agree that this doesn't turn it into a big effort :-)
The mechanism could be extended in two directions:
1) Apply it to other settings that have an effect until end-of-text.
2) Generate an implied (:revertlinebreaks:) when exiting from an include
file. That would implement what Crisses wanted, with little effort.

That would require everybody to go through templates and add
(:nolinebreaks:) everywhere. That's a lot of work, and it's too easy to
overlook a place where it would have to be added.
Plus, things tend to get ugly if they want (:linebreaks:) in some parts
of their site and (:nolinebreaks:) in others. At that point, most people
start fiddling with moving the directives from the include files to the
places where they are included and vice versa, and the final result is a
I think having undoable setter directives would be far better :-)
