top: make user's choice for insert/overtype persistent

When true line input editing with paste capability was
was re-introduced in the commit below, the concept for
the distinct insert/overtype mode was also introduced.
But such a distinction did not survive an <Enter> key.

With this commit, the cursor state is made persistent.

(everything is perfectly justified plus right margins)
(are completely filled, but of course it must be luck)
