[R] Fwd: string

[Gabor Grothendieck]

Some new syntax to handle this without escapes was on my wish list for
R and keeps coming up from time to time. As mentioned it would also be
useful for latex source, Windows path names, regular expressions and
other situations such as this one which require characters that
otherwise need to be escaped.
