patch 9.1.0574: ex: wrong handling of commands after bar

Problem: ex: wrong handling of commands after bar
Solution: for :append, :insert and :change use the text after the bar
as input for those commands. This is what POSIX requests.
(Mohamed Akram)

See the POSIX Spec:
https://pubs.opengroup.org/onlinepubs/9699919799/utilities/ex.html#tag_20_40_13_03
