This works for Tramp 2.0. It will work for Tramp 2.1 too, but there
are also other means to derive a default methold. For the time being
you might use a comment for this.

I know. This problem has eaten most of the time yesterday. In fact I
don't know a safe decision whether a file name shall be completed only
or "applied". Therefore I've introduced a new variable
tramp-completion-mode, which is set in
file-name-all-completions. Sensible Tramp file name functions, which
need to behave depending on the mode, check this variable (beside
other checks). So you might use it as well (untested, I'm @work):

(let ((tramp-completion-mode t))
  (file-directory-p "/telnet:kfs@"))

Best regards, Michael.
