checkpatch.pl does not recognize #elif as a preprocessor directive

causing it to print bogus errors for, e.g.:

ERROR: need consistent spacing around '&' (ctx:WxV)

when the operator is not recognized as unary in this context.
for example:
void foo(void)

{

	int x, y, z;

	void *p[1] = {

#if defined(X)

		&x

#elif defined(Y)

		&y

#else

		&z

#endif

	};

}

Yes, thanks; good catch.  Commited this and added tests for it.

Will be in 0.13 which is imminent.
