That's a sensible idea.  I think it should act like narrow, but you are
not allowed to widen, only redefine the narrowing criteria (line
region/byte region/regular expression/etc) and you can also grow/shrink
the window up to a practical limit.  Most of such a mode's filtering
functions should be implemented in C, so it's not an easy task.
