GNU diff -p does "^[[:alpha:]$_]"; personally I think any line
that does not begin with a whitespace is good enough.

Obviously I was not thinking.  That should at least be "any line
that begins with a non-whitespace and has a few characters", to
omit "{\n" and catch "int main()\n" in:

	int main()
        {
        	printf("Hello, world.\n");
        }
