multiline string/string literal without escape processing

[Per Bothner]

IMO more valuable that multiline string/string literal without escape 
processing
would multiline string/string literals with embedded expressions.  For 
example,
to pick some arbitrary syntax:

   #"The percentage is \{a * 100.0 / b}%."#

This lends itself to template processing, easier-to-use 
internationalization,
less error-prone println calls, and more.

A pure literal multi-line string without embedded expressions seems to be
much less useful.  Yes, it would be nice to avoid backslash-explosion,
but that's mostly a factor in regexps and Windows filenames, which are
unlikely to need to be multi-line.
