/*
* '\\' has a special meaning on phase 2 if and only if it is immediately
* followed by '\n'. In any other position it's left alone as any other
* character.
*
* [5.1.1.2(1.2)]:
* Each instance of a backslash character (\) immediately followed by
* a new-line character is deleted, splicing physical source lines to
* form logical source lines. Only the last backslash on any physical
* source line shall be eligible for being part of such a splice.
* A source file that is not empty shall end in a new-line character,
* which shall not be immediately preceded by a backslash character
* before any such splicing takes place.
*
* Note that this happens on the phase 2, before we even think of any
* tokens. In other words, splicing is ignorant of and transparent for
* the rest of tokenizer.
