Why allow concatenation of string literals?

Question

I was recently bitten by a subtle bug.

char ** int2str = {
   \"zero\", // 0
   \"one\",  // 1
   \"two\"   // 2
   \"three\",// 3
   nullptr };

assert( int

So that you can split long string literals across lines.

And yes, I've seen it in production code.
