You can always get around that by reading the script with -f instead.
On balance I can see a lot more uses for read-from-stdin than the other;
however, we do need to define what happens if the command appears when
commands are coming from stdin.
Would it make sense to say:
1. if pset.notty is set and '-f' switch is not set then use simple_prompt
-- deals with SQL script redirection case and '-f' is not used, and
2. else then use gets_fromFile(stdin) <or some other alternative?> (read
-- deals with "prompt value" redirection case and '-f' is used, or
It appears that pset.notty will get set to 1 when stdin is not a tty device,
which should be the case for redirection.
