When we look through the index from (truncated number) to (real end number) we get every channel, which is too large to encode, so we iterate again. This fixes both that problem, and also the issue that we'd end up dividing into many empty sections until we get to the highest block number. Instead, we just tack the empty blocks on to then end of the final query. Reported-by: George Vaccaro Signed-off-by: Rusty Russell <[email protected]>

When we look through the index from (truncated number) to (real end number) we get every channel, which is too large to encode, so we iterate again. This fixes both that problem, and also the issue that we'd end up dividing into many empty sections until we get to the highest block number. Instead, we just tack the empty blocks on to then end of the final query. (My initial version requested 0xFFFFFFFE blocks, but the dev code which records what blocks were returned can't make a bitmap that big on 32 bit).
