[Cocci] Newline escape in preprocessor

[Mansour Moufid]

Hi,

I'd like to add a statement after another within a preprocessor
expression, but spatch adds the line without an escape (backslash).

x.c:

    #define X(a) x(a);

(I know the above is not technically correct but it's super common.)

x.cocci:

    @@
    expression e;
    @@
        x(e);
    +   y(e);

output:

    $ spatch --sp-file x.cocci x.c
    HANDLING: x.c
    diff =
    --- x.c
    +++ /tmp/cocci-output-80658-7f90b1-x.c
    @@ -1 +1,2 @@
     #define X(a) x(a);
    +y(a);

I can think of two solutions, if an expression is inside a
preprocessor statement: add a backslash before every newline, or skip
the newline.
