Hi,
in general I see where the enhancements are coming from - but I do have
some comments.
One is pedagogical; I think a world where single line strings are
denoted by a single double quote, whereas multi line strings are denoted
by triple double quotes is a relatively wimple world for the user to
grok. This proposal effectively blurs the line between the two variants,
as now you can (in the degenerate case where all lines in a text block
ends with '\') express a single line string with a text block syntax -
which I understand is the part of the goal, but...
The other perplexity is on the use of \s with text blocks; I don't get
why the output in your example ends up being:
red<one space><new line>green<one space><new line>blue<one space><blue line>
Why is the space at the left of the '\s' being ignored? In fact, '\s' is
the _only_ thing you can put in that place that will cause the previous
space to be ignored and dropped on the floor, which makes me
uncomfortable. I think that, to get the output you want, '\s' should be
close to the end of red/green/blue - if, on the other hand, if you add
space and _then_ you add a '/s', I don't think we should treat this
differently from adding space and then some _random_ character - in
which case all the space in between will be preserved.

During the discussion on Text Blocks, several of you stated a need for a line
continuation construct. I have since created a CSR to propose the creation of two new
escape sequences: \<line terminator> and \s.
