[Bug preprocessor/35010] New: preprocessor loses leading whitespace

["sabre at nondot dot org" <gcc-bugzilla at gcc dot gnu dot org>]

This testcase:

#define debug(format, ...) format, ## __VA_ARGS__)
debug(X);
debug(Y, 1, 2);
debug(Y, 1, 2 );
debug(Z, );
debug(W,);

Should preprocess to:

X);
Y, 1, 2);
Y, 1, 2);
Z, );
W, );

not:

X);
Y, 1, 2);
Y, 1, 2);
Z,);
W,);


Z/W should have spaces.
