In C I like constant string concatenation more than backslash 
continuation, because strings are clearly delimited and indentation can 
be used to keep things tidy and aligned, both in human-written and 
computer-generated code:

  printf("Please make your choice:\n"
         "<R>un\n"
         "<Q>uit");

That said, I think any change introducing incompatibilities in Lua 
should be carefully evaluated, especially as we already have compiler 
concatenation (or is it the loader? I forgot and couldn't find it in the 
manual):

  io.write("Please make your choice:\n" ..
           "<R>un\n" ..
           "<Q>uit");

By the way, is there a high extra cost in the case of a large number of 
strings concatenated in this way?
