I had some time to track this issue: the download is not aborted
because there is an infinite loop in ssh_easy_statematch when ssh
connection state is SSH_SFTP_SHUTDOWN.

By the way, there is a similar problem with ssh
(infinite loop with state SSH_SESSION_HANDLED).

And for the progress meter: It updates itself with SFTP, but is stuck
with SSH after authentication.

This simple patch fixes the timeout (I guess there is a more graceful
way to handle disconnections):

diff --git a/lib/ssh.c b/lib/ssh.c
index a0ca4c5..9e10317 100644
