 I think connecting both rl_outstream and stdout to `/dev/tty` is probably
 the least surprising behaviour.  Then the user gets a switch into a fully
 interactive mode on their tty and stdout is no longer piped to the file.

 Today I came across the combination of `augtool -ief foo` not working
 (`Failed to reopen stdout: No such file or directory`) which is very
 similar.  It seems the best course is to only re-open rl_outstream when
 not connected to a tty, but then to re-open `/dev/tty` as you suggest.
