`io.input().remaining()` acting weirdly

[vifino]

while true do
  print("pre-read", io.input().remaining())
  print(io.read(1))
  print("post-read", io.input().remaining())
  os.sleep(1)
end

Results in https://puu.sh/vItFy.png when typing. Really weird stuff.

Magik6k | vifino, idk, it might be returning number of buffers in pipe waiting for read instead of len. Will look into when I'll have some time for mc. Can you make an issue in plan9k repo?
