Dear list,

I have a question about using the shell and ssh.  Firstly, I've already
been through the pain of getting Delete, Backspace, Home, and End to work
in both local and remote shells, as well as vi.  I'm a bit disappointed
that these things are not already in place, as they are in Linux.

I'm using iTerm, as it seems to have better defaults, and it does tabbed
terminals, but Terminal.app tends to suffer the same ills.

Anyway, my question is about using backspace while a program is running.
The main example of this is when I ssh to a server and the key password
prompt comes up.  If I know I made a mistake typing in Linux, I can just
hit backspace a number of times (even though the cursor never moves), and
retype the password, no problem.  But in OS X iTerm, the backspace gets
sent as ^H in this circumstance, and so there's no way to back up over
your input.

Another illustration of this is using an rsync command that runs a while
(this is the reason I know that ^H is sent rather than backspace).  Say
I'm running a rsync on large amounts of data and it takes a while to run.
Like so:

rsync -a /big/files /backup

Now, normally, as I'm sitting there waiting, I can type another command
and hit enter and that command will execute after rsync finishes.
However, what if I notice my syntax for the next command is wrong or I
mistyped?  In Linux, I can just backspace over what I typed.  But in OS X
iTerm, I get ^H printed out for every backspace.  How do I fix that?
