Public bug reported:
I use the following SSH configuration options:
ControlMaster auto
ControlPath ~/.ssh/.socket-%r@%h:%p
ControlPersist 60
It looks as if it's configured correctly because opening multiple
connections using the same username and host-port combination shares the
first connection.
[Enter], [~], [.] closes each session individually, which is great.
However, that disconnect escape sequence appears to do absolutely
nothing if the multiplexed connection dies abnormally (for instance, if
my WiFi connection dies), which is the time when I most need the
disconnect sequence to work, since I'm not going to be doing much on
that dead session anymore, and I'd like to restart it.
[Enter], [~], [.] works fine on a *nonmultiplexed* connection when it
dies abnormally.
