You can't reconnect to a broken ssh connection, and in fact it
should have killed all the processes you were running.  However,
some editors will save your work when terminated abnormally and
let you recover in a different session.  For example, if you used
vi filename
and were disconnected, you could recover later with
vi -r filename
I don't know anything about nano, though.
