This case, I'ld like to see a backtrace for analyzing.

tramp-file-name-structure reflects a regexp for unified
filenames. tramp-file-name-regexp and file-name-handler-alist are
valid for "separate" filenames. How does this happen?

tramp-unified-filenames, tramp-file-name-regexp and adding of
tramp-file-name-handler to file-name-handler-alist are autoloads. They
are executed _before_ your .emacs (or .xemacs/init.el), i.e. setting
of tramp-unified-filenames is too late in your init file.

tramp-file-name-structure is not an autoload. Therefore, setting
tramp-unified-filenames in your init file takes effect.

If you want to have unified Tramp filenames, you need to disable the
autoload for Tramp in XEmacs. Personally, I do change file permissions
to 000 for .../xemacs-packages/lisp/tramp/auto-autoloads.el*
