The # sigil now ignores everything that's indented further than the sigil:
Nuit #foo bar
qux corge
@nou yes
maybe someday
@not included
JSON ["not", included"]
---
The ` and " sigils now have significantly different indentation rules. In particular, `foobar is now invalid: there must always be a space after the sigil. This change means that you can now include spaces at the front of a string without using a Unicode escape:
Nuit ` foobar
JSON " foobar"
---
The " sigil supports two new escapes: \s inserts a space and \n inserts a newline. These are just conveniences for \u(20) and \u(A) respectively. This makes it a lot easier to include spaces at the end of a single-line string.
---
I got rid of the \ sigil because it's not necessary: you can just prefix the line with ` or " to get the same effect.

I specified that strings within a Unicode escape must be separated by only one space. That means this is valid:
"I specified that strings within a Unicode escape must be separated by only one space."
Drat. I thought of it as a nifty way to split a large chunk of escape sequences over multiple lines. It's not like I was ever going to want to do that, though.
That was actually never possible, because of the way the parser chunks the stream into lines and then operates on each individual line. I had considered making it possible... but I think that would have been too confusing. And it would have been far too little gain for too much work...
