Hi again,

	Here is a second proposal to complete the previous one: this patch allows the 
use of $x or @x identifiers ($1 ... $n and $#, etc) during the preprocessing (in 
addition of kernel_v pattern, etc).
	Again, I originally have written this for a colleague and found this useful.
	So again:

Thanks
