set the OUTPUT_RECORD_SEPARATOR like say() does

I was surprised by this, and then noticed that you were referring to the say docs. However, IMHO they're wrong, say doesn't seem to set a local $\, so I just filed bug #134298 to hopefully clarify/fix the documentation.

Update: A patch has been applied, the say docs in the next release will say:

Just like print, but implicitly appends a newline at the end of the LIST instead of any value $\ might have.
