Okay, that was my .tcshrc, in which I had this check:
if ( $term == "xterm" )

on a non-interactive session, $term is not set and it
coughs like "term: Undefined variable", which must've
messed up the sftp handshake.

Now, having tcsh as my login shell and sftp working as well,
I couldn't be happier.
