+1.  My vote is for backslash continuations.  Inferred continuations
require you to end your expressions in places where they can't legally
stop, so you can't do

\set x 2
+3

will not do the same thing as

\set x 2+
3

I don't want to get into a situation where every future bit of pgbench
syntax we want to introduce has to worry about what the interaction
with inferred continuations might be.  Backslash continuations are
kind of ugly, but it's a simple rule and virtually everybody who is
likely to be writing pgbench scripts will understand it immediately.
