Ummm... the assignment to f is problematic.  Let's change it a bit:

	f = x + 7
		*p++

Now, is this one statement or two?  I strongly suggest that if
you want to have a syntactic rule for continuing a statement,
you make it a lexical rule instead, as in EFL.  Thus, if the
last token on a line is {insert list here}, the statement is
continued.  The list would be exactly those tokens that cannot
ever end a statement, such as ( = + - * / and so on.
