New Revision: 198185
URL: http://svn.freebsd.org/changeset/base/198185
Log:
Print backspaces after echoing an EOF.
Applications like shells expect EOF to give no graphical output, while
our implementation prints ^D by default (tunable with stty echoctl).
Make the new implementation behave like the old TTY code. Print two
backspaces afterwards.
