(I'm going through old bug reports that unfortunately weren't resolved
at the time.)

I don't think we can change the behaviour of these commands, because
that would be annoying to many users that are used to the current way
they work.

Unfortunately, the prefix argument is already taken there.

In addition, "remembering" this data is kinda tricky -- we allow saving
registers to file, and we'd have to extend the on-file format, etc.
Everything's possible with a little programming, of course, but the
interface problems are more difficult -- I don't immediately see any
good way for the user to specify that it's a point-at-the-end register.

We could add a special command for that, but...

Hm...  perhaps we could make `C-u' for insert-register "sticky" for that
register?  That is, if you `C-u C-x r i a', then that "a" register would
keep that behaviour for the rest of the session (until toggled off with
a subsequent `C-u C-x r i a', perhaps).

But that's a pretty convoluted interface, and changes the current
behaviour.

Anybody got any ideas here?
