[R] Difference in lexical analysis of strings in R and S-PLUS?

It appears that R (1.3.1, Solaris and Windows) tokenizes strings differently
than S-PLUS (6 on Solaris and Windows).


> foo <- "abc
Continue string: def"
> cat(foo)


> foo <- "abc
Error: syntax error

This difference occurs in source'd files as well. Is there a way to get the
S-PLUS's (and perl's, lisp's, etc.) view of strings, or am I going to have
to go thru my many, many files and escape multi-line strings with
backslashes? What am I missing here?
