scp user at host1 user at host2 broken?

[Pekka Savola]

Hello all,

Is it just me or is 'scp user at host1 user at host2' broken (if the server asks
you for the password)?

1) [password required]

>From OpenSSH 2.5.1p1 -> OpenSSH 2.5.1p1 -> OpenSSH 2.3.0, I get like:

> scp pekkas at xxx:~/*.patch psavola at yyy:~/temp/
 psavola at xxx's password:
 You have no controlling tty.  Cannot read passphrase.
 lost connection

2) [protocol1 (different host), no password required]

$ scp pekkas at xxx:~/*.patch pjsavol3 at zzz:~/temp/
pekkas at xxx's password:
/home/unf/openssh-SNAP-20010219-redhat-init-functions.patch: No such file
or directoryselect: Bad file descriptor

NOTE: ~unf (the username in the originating host) is used instead of
forced pekkas at netcore.fi!

NOTE: a bad file descriptor warning.  I believe this will happen if you
use full path names instead of '~' etc.

Also, -P -flag is ignored in host-to-host copy.  Looking at the source,
this appears to be intentional (ie: which definition should that apply
to?)

Longer log of case 2):
