Apparently bash's behavior is to replace <any amount of whitespace,
backslash, newline, any amount of whitespace> with a single space
character, and that at least seems like a *useful* behavior for us too if
we're open to it.
Which raises another question: do we allow \<terminator> in SL strings? (I

Hmm, I can see how that could be harmless but it seems to blur the boundary
between the features to me.
But I've lost track of why we need triple-quote to be different from
single-quote in the first place. *Could *the notion just be that if you
newline immediately after opening quote then you are asking for MLS with
everything that comes along with that?
Oh, and quite a few of *those* use cases are in annotations like

So sorry: I meant vs. 6 months ago, not that this is new.
I know I complained about our going back to the drawing board then, but
where this thread is going now is making us much happier than before.
