Unlike WS_Alloc() it fills the allocated space with the result, which
should be considered constant at this point. And on top of that it's

Required fields work like inclusion filters, except that not matching

They map directly to VSC 'I' and 'X' arguments.

And simplify the 'f' argument handling.

Instead we now have a single list that works on a first-match basis,

rather on the number of characters missing until the end of the current
block of four.
