ui: disable echo back of prompt input if ui is set to non-tty purposely

9ab18a912c44 is nice for test output, but it also affects command-server
channel.  Command-server client shouldn't receive echo-back message, which
makes it harder to parse the output.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
