Please follow SubmittingPatches (missing signoff, weird use of scissors
marker that cuts out your commit message, and your commit message should
summarize the discussion).

Is that right? The "out" fd is where we send sideband 1, and it is
almost always not going to be a tty. The suffix should be sent with
sideband 2, which goes to stderr. So I'd think you would want to check
isatty(2).

Also, most isatty checks also need to cover the case that a pager has
already been started.  That is probably not worth worrying about here,
though, as we shouldn't be using a pager for commands that do network
communications (and if we do, omitting the magic line-clearing signal is
probably a sane thing to do).

I think the overall goal is a step in the right direction, though.
