Synopsis: Incorrect handling of escaped newlines

State-Changed-Why:
    This was a deliberate decision, and is documented.  It also produces a diagnostic that cannot be turned off.
    
    We believe that translation phase 1 of the standards gives us leeway to do this, and could not conceive of conforming code that would be effected.

>Description:
According to the standard, a backslash separated from a
newline by whitespace is not eligible for line splicing.
If, for compatibility, this feature is to be retained it
should be made available via command line switch which
defaults to off (i.e. to behave conformingly by default).

Just examine the relevant code in skip_escaped_newlines.
