I am not sure of the spec to which you refer but R7RS Section 6.7
includes, in the itemized list of escape sequences,

  \<intraline whitespace>*<line ending>
  <intraline whitespace>* : nothing

which is the behavior you observed in Kawa, etc.

I find it to be a useful feature for fitting long strings in nicely
indented code.
