What about the Python approach: The literal text is enclosed either in a pair of three single quotes or three double quotes. So you can do (e.g. in the python shell)
It'll only make plpyhon functions harder to write, if you need to use longstring quoting INSIDE your plpython functions yourself, e.g. documentation strings.
'Here' documents seems like the most sensible solution to me so far.
