jffs2reset produces no output when run by ssh directly

[bam80]

Normal operation:

$ ssh root@openwrt

root@OpenWrt:~# jffs2reset 
This will erase all settings and remove any installed packages. Are you sure? [N/y]
N
root@OpenWrt:~#

When run with ssh directly, no output produced:

$ ssh root@openwrt jffs2reset
# waiting for input here
N
$

I found a workaround for this by running ssh with -t option:

-t Force pseudo-terminal allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services.
