Dear tramp-devel,

I am trying to connect to a remote that is behind a proxyjump in my SSH
config. It is described as follows:

Host host2
  SetEnv TERM=xterm-256color
  HostName host2
  ProxyJump rnagpal@host1
  User rnagpal
  LocalForward 8888 localhost:8888

Host host1
  HostName host1
  User rnagpal
  LocalForward 8888 localhost:8888

With a terminal, I am able to ssh without issue via `ssh host2` however I
cannot do it with TRAMP async-shell-command nor eshell. However, I can do
it via term from within emacs. Furthermore it works by piping `/ssh:host1 |
/ssh:host2`

But just using `/ssh:host2`
I get the following error:
```
bash: No such file or directory
Connection closed by UNKNOWN port 65535
```
TRAMP log with verbose level 7:
```

host2 || exit

"\(.*\(?:login\|user\)\(?:[[:blank:]].*\)?:[[:blank:]]*\)\'" from remote
shell
```

I thought the issue may be related to:
https://emacs.stackexchange.com/questions/24159/tramp-waiting-for-prompts-from-remote-shell
However after removing my .bashrc and .profile on both hosts the issue
still persists.

Any ideas on what to do?
