Yeah, it's always done that. libedit thinks it should do chmod()
on the target file, which while not inherently unreasonable is
guaranteed to spit up on /dev/tty.
Another problem with implementing \s-to-display as save-to-/dev/tty
is that if something did come out, it would be in libedit's rather ugly
encoded format. libreadline happens to save the history file without
any decoration, but it's improper of us to depend on that.
We really ought to get rid of that implementation entirely and have
a separate code path for \s-to-display, which for extra credit could
go through the pager.
