Thanks for the '-bar' tip!
However, including -bar in my definitions for both
RTPrestore and RTPtemp, does not appear to cause the :sil to
apply to more than the RTPtemp.
You cannot just put bar-separate sequence of commands under :silent.
In the bar-separated sequence of commands, you need to
prepend :silent to every command.
You can try [to give yourself problems] by something line
:silent exe "cmd1|cmd2|cmd3" but this will not work for you
because of helpg, and yuu'll need really elaborate
embedded quoting.
I suggest that you stick to sil cmd1|sil cmd2 |sil cmd3
