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

From the python lexical analysis reference, section 2.4.2:

This feature can be used to reduce the number of backslashes needed, to split long strings conveniently across long lines, or even to add comments to parts of strings
