That's the intention of my change. You shall get more information where
to look for.

We have kept out the trailing colon in `tramp-shell-prompt-pattern',
because often you get information or requests during login with such a
trailing colon, which should not be recognized as prompt. Like this:

Password:

So from my pov, this bug is resolved. I recommend you to use a prompt
w/o a trailing colon. Or you modify `tramp-shell-prompt-pattern', as you
have done.
