That's the principle, but not what happens with gcc...

Phase 2 says, "Each instance of a backslash character (\) immediately followed
by a newline character is deleted, splicing physical source lines to form
logical source lines.", and explicitly states that, "Only the last backslash on
any physical source line shall be eligible for such a splice.".

I wonder if all trailing white-space is being trimmed from each source line
before or during the first Translation Phase?
