So is it basically just multi-line doctests with slash continuation chars
we have a problem with? Those were always a bit ugly - but seemed
the best solution given the desire to limit ourselves to 80 character
lines.

Could you make them single liners for now (least work to get the tests
to pass), and I'll take a look at the commit later. If these are from my
examples I'll then have a think about how better to handle them.
