Symbolically, || points Stata 8 and 9 users onwards and upwards
(recall that only in 9 do you get arrows).
Syntactically, this was introduced in Stata 8. Have a look
at [G] graph twoway.
In 9, the separator notation has been applied elsewhere,
with -xtmixed- success.
Unix-lovers will recall the pipe notation of their favourite
OS (imitated in a broken way by MS-DOS).

P.S. you are right that I assumed people would realise
this was a single command line.
