tramp doesn't work for me in 26.1 but does in 25.3

Same .emacs.  I'd like to debug it, but I've spent 30 minutes looking
through tramp.el (in 26.1) and comparing various variables, side by side,
in 26.1 and 25.3.  No diffs, so far.

When I C-x C-f /machinename:/dir TAB I get nothing.  I do (require 'tramp)
and in 25.3 when it starts up I see various messages in the minibuffer:

Tramp: Opening connection for rick using scp...
Tramp: Sending command ‘exec ssh   -o ControlMaster=auto -o
ControlPath='tramp.%r@%h:%p' -o ControlPersist=no -e none rick’
Tramp: Waiting for prompts from remote shell...done
Tramp: Found remote shell prompt on ‘rick’
Tramp: Opening connection for rick using scp...done


On 26.1 I see none of these (even looking through *Messages*).

tramp-default-method is the same in both versions (scp).


Ideas?  Thanks.

Btw, in emacs -q with just (require 'tramp) it doesn't work either.
Operating system is CentOS 6.9.  Built on that machine.

Tramp now requires an explicit method component in the filename.

Relevant NEWS entries are:

*** The method part of remote file names is mandatory now.
A valid remote file name starts with "/method:host:" or
"/method:user@host:".

*** The new pseudo method "-" is a marker for the default method.
"/-::" is the shortest remote file name then.


So either of these should work in Emacs 26:

C-x C-f /-:machinename:/dir
C-x C-f /scp:machinename:/dir
