Hi Neil,
Not that I know of, but I use exactly the method you noticed, the 
trailing operator. There was a discussion similar to this not long ago 
about the use of the semicolon as a line terminator. If the trailing 
operator is a problem, you can wrap the whole statement in parentheses:

x<-(c(1,2,3,4)
/c(1,2,3,4))

or even:

(x<-c(1,2,3,4)
/c(1,2,3,4))

The interpreter will assume that more input is needed from the 
unbalanced parenthesis in the first line. An unbalanced quote would also 
cause the interpreter to wait for more input, but I don't think it would 
be of any use in solving your problem.
