Title:
  rust-coreutils: tee is buffered

Status in coreutils-from package in Ubuntu:
  New
Status in rust-coreutils package in Ubuntu:
  Fix Committed

Bug description:
  The uutils version of tee is line-buffered, but GNU coreutils tee is
  unbuffered. This breaks the Java test suite, for example, which writes
  a single byte 'a' and then tries to read it.
