paste: fix normal-mode paste by different approach #10976
Forcing insert-mode after the first paste-chunk seems to work, as an
alternative to a9e2bae0eb (insert-before-cursor).

NB: Dot-repeat needs to match the original action.  Since a9e2bae0eb
changed paste to insert-before-cursor, dot-repeat must also. But that
makes dot-repeat unpleasant/unusual.
