OK, I see... I wasn't aware Tramp is being developed outside Emacs
CVS. There is no point in applying my patch in this case.

I have tried Tramp-2.1.3, but it doesn't work for me at all. I get 
"format-spec: Invalid format string" error from macro at line 5783 of
tramp.el, in defun tramp-maybe-open-connection.

I will try to investigate further when I have time.

A couple of those look interesting, although neither is as easy to use
as default user name :)

I tried that. When I do:

(setq tramp-login-prompt-regexp "[Ll]ogin\\( as\\)?: *")

my "login as:" prompt gets recognised and tramp proceeds trying to
login using my user-login-name... cool :) 

Except there is, apparently, a bug which causes tramp to strip last
letter from user name (i.e. if my user-login-name is "slawek", tramp
tries to login using "slawe").

Setting user-login-name to "slawekX" seems to work for me at the
moment ;) I don't have any more time to hunt this bug right now, but
I will try to figure it out later.

Thanks for your ideas.

If the code and the comments disagree, then both are probably wrong.
