Well, the position would logically get changed after the editor has
returned the data, but before curses is turned back on, and the screen
redrawn.

For some of the other proposed functions, I *think* curses would still
need to be turned off and back on while the new anchors were being
added, but in any case, a redraw would be needed after the operation
is completed (again ... I think).

BTW, I'm thinking that if the cursor ends up getting moved past the
screen boundary, that I'd like to have the target line/anchor show up
in the (approximate) middle of the screen.  Of course that's a refine-
ment; what I need to figure out first, is just how to move the cursor
at all ...!

's'ok ... I left a BIG COMMENT at the tail end of Gridtext.c, where
the cursor movement needs to happen ... :-) ...
