ui: show prompt choice if input is not a tty but is forced to be interactive

The tests often set ui.interactive to control normally interactive prompts from
stdin. That gave an output where it was non-obvious what prompts got which
which response, and the output lacked the newline users would see after input.

Instead, if the input not is a tty, write the selection and a newline.

  $ hg init
  $ touch a

  $ echo "username= foo" >> .hg/hgrc
  $ echo "          bar1" >> .hg/hgrc
