Then this needs to be fixed.  Looking at the code, I can't quite
understand what it does: it seems that Tramp's method/user/host
completion is only activated for people you use either
partial-completion-mode, ido, icycle, or XEmacs.  I'm not sure what's
the logic behind it, but I'd rather just activate it based on a specific
configuration variable (or just always activate it, as you do in
XEmacs).  In Emacs-23, the functionality that was previous offered by
partial-completion-mode is enabled by default (tho implemented
differently and activated differently as well).
