Bug#326800: ssh: scp password prompt does not cleanup terminal on Ctrl-C

["Silas S. Brown" <ssb22@cam.ac.uk>]

Package: ssh
Version: 1:3.8.1p1-8.sarge.4
Severity: normal


If you press Control-C at scp's "Password" prompt, you get
dropped back to the shell prompt but subsequent commands are
not echoed as you type them (only the prompt and the output
is visible).  For example, here I pressed Control-C at the
prompt, then pressed Enter a few times and then typed "ls":

ssb22:~$ scp /tmp/resume2.ps beethoven:
ssb22@beethoven's password: 
ssb22:~$ 
ssb22:~$ ssb22:~$ ssb22:~$ #%=2Ascratch=2A#       greetings.lyx     #newfile3.lyx#   resume.tex.m4~

This bug only happens with scp, not with ssh.
