[MIT-Scheme-devel] forcing left-insertion or right-insertion in Edwin

[Taylor R. Campbell]

Is it possible to force left-insertion or right-insertion of
characters in Edwin, so that any permanent marks at the desired
position will not be shifted?  Alternatively, is there a better way to
do this sort of thing?  SAVE-EXCURSION isn't entirely working for me
-- insertion at marks equivalent to the original point moves the point
even after SAVE-EXCURSION returns, because SAVE-EXCURSION created a
permanent copy of the current point, so inserting at that position
moves it.
