wireprototypes: clarify documentation of getbundle argument types
It seems like it was a mix of what the Python code would see and what
was sent over the wire. I've tried to clarify both the type seen in
Python and how it's transmitted.

potherp1 is a boolean variable that means "pother is ctx.p1", and parents is
naturally [ctx.p1, ctx.p2].
pctx is always removed from parents, so if pctx is parents[0], then we end up
using parents[1] as pother. To be true to its name, potherp1 should then be
True only when pctx is at parents[1].
