RE: rectangle operations - narrowing? |

What I'd like to do, to start with, is, in effect, "narrow"
to a region that has the content of a given rectangle of text.
The idea would be to operate on this region in some way, and
then widen again - in effect putting the (possibly modified)
rectangle back in context.
Ordinary narrowing limits what redisplay includes. But I think you
would want this new rectangle narrowing to have no effect on redisplay.
Right?
No, I'd be fine if it worked exactly like narrowing, I think. If I narrow
interactively, then only the region is displayed (redisplay wipes out the
envelope outside the region). But if I do `save-restriction', narrow,
fiddle, then widen, the user never notices the temporary narrowing.
