this is how i found it: i had a piston facing up, i put a redstone block on top. nothing. then, i put a block beside the base of the piston, and i put a redstone dust on top of that. the piston should extend. the you can break the redstone dust + the block it was on. the piston stays extended. this also works if you have 2 redstone blocks on top of the piston. then all you have to do is put a block (i used stone) beside the piston base and voila. the piston extends!

a) Pistons can be powered from two blocks above.
b) If said block changes, piston wont be updated.
This is (at least temporary) intended behavior
Like following:
place piston, place 20 blocks in front of it, power piston — not extending. Break any block from second to 12th — still not extending. Place any block besides piston — extending
