IDE (IntelliJ IDEA) support for Raw String Literals

I think there are two cases:
- when you're at the _end_ of the string and the next character is the
auto-inserted close quote;
- when you're in the _middle_ of the string.
For the first case, I think treating it as you do with double-quote in
regular strings is right; most of the time, when I type tick-stuff-tick,
I am ending my raw string literal, so ticks at the end of the string
should be considered to be the closing delimiter(s).
For the second case, you've already got a well-formed RSL, and you're
adding stuff in the middle. I would bias towards (1), with the option
of an intention to add (or subtract) more ticks to the delimiter. (The
intention should skip over tick counts where the body would collide with
the delimiter, and I'd think this should always be available on RSLs,
regardless of whether I'm typing more ticks in the middle or not?)
If what I want to do is break the thing up, I'll probably just type
tick-plus-stuff-plus-tick, and if I ignore the offered intention, I'll
get what I want.
