apply -0 to stdin/-i as well

while i was initially against this since it can be done via `xargs -0`.
the problem with this approach is that there's a limit to how many args
a command can recieve, leading to problem like this [0] when opening
large (1k~) amount of images.

there's no limit on how big stdin can be, so being able to read a
null-separated list from stdin doesn't have this problem.
