Re: multi-region.el --- Mapping commands over multiple active regions.

[Richard M. Stallman]

I was going through old mail and came across your posting
of multi-region.el, last January.

Can someone imagine a way to integrate this into Emacs, so that
ordinary Emacs commands, which now operate on the region, could
operate on multi-regions when the user has specified multiple regions?

Here's one idea.  Suppose that region-beginning returned a list of
region beginnings, and region-end returned a list of region ends.
That would be a clean way to tell a command that there are
multi-regions in effect.

This could be done for (interactive "R"), whereas use
of (interactive "r") would simply repeat the command on each
sub-region in the list.

Now is not the time to install such a change, but we could think about
it now.
