Tramp has already such a function `tramp-error-with-buffer', which ought
to provide such information. It does not seem to work robustly under all
circumstances; I'm working on this.

Another problem is, that Tramp is just a library. That means, if you
want to open a file, several Tramp functions are called independently,
each of it requires an established connection. There must be a mechanism
that during a given timespan (let's say 5 seconds) Tramp does not try to
reconnect after a failed connection attempt. This works already in some
special cases; I'll improve this as well.
