Unwanted Interaction between Tramp and fish shell

[Doherty, Daniel]

I have started using the fish shell, which I like for interactive use.  I have set it to be my default shell with chsh. 

However, it does not play well with TRAMP, which uses the 'COMMAND && COMMAND' syntax in several places.   When I open a file in a remote dir over TRAMP, I get and error complaining about fish not implementing the && construct. 

I believe TRAMP always uses /bin/sh as the shell on the remote side, so I'm guessing this is invoking it on the local side. 

The error message pops up in a *temp* buffer, which goes away when I type anything in it, but it says something like this: 

Unsupported use of && ... 
fish: scp -p -q -r ... && echo tramp_exit_status 0 || echo tramp_exit_status 1 

I have tried setting explicit-shell-file-name to "/bin/bash" and setting SHELL environment variable to "/bin/bash" with setenv when tramp is loaded. None of this has helped.

Here is what from the debug buffer with tramp-verbose set to 8:

Any idea what is happening?
