Speaking of which, it seems to me that :p and :c should allow an argument that says where to start relative to the current position. In other words, :p means :p(0) and :c means :c(0). I could also see uses for :p(-1) and :p(+1).
Isn't that slightly inconsistent with :p meaning :p(1) the so-called "real winner for passing boolean options" of A12? -- TSa
