* net/tramp.el (top): Put load of all tramp-* files into a dolist.

Require tramp-cmds.el.
(tramp-make-tramp-temp-file): We can get rid of DONT-CREATE.
(tramp-handle-file-name-all-completions): Expand DIRECTORY.
 (tramp-do-copy-or-rename-file-directly): Make more rigid checks.
(tramp-do-copy-or-rename-file-out-of-band)
(tramp-maybe-open-connection): Use `make-temp-name'.  This is
possible, because we don't need to create the temporary file, but
we need a prefix for ssh, which has its own temporary file
handling.
(tramp-handle-delete-directory): Add "-f" to rmdir.
(tramp-handle-dired-recursive-delete-directory): Call "rm -rf".
(tramp-handle-insert-file-contents): Don't raise a tramp-error but
a signal, in order to give the callee a chance to suppress.
(tramp-handle-write-region): Set owner also in case of short
track.  Don't use compatibility calls for `write-region' anymore.
(tramp-clear-passwd): Add parameter VEC.  Adapt all callees.
(tramp-append-tramp-buffers): Apply `tramp-list-tramp-buffers'.

* net/tramp-cmds.el: New file.

* net/tramp-gw.el (tramp-gw-basic-authentication): Apply VEC to
`tramp-clear-passwd'.

* net/trampver.el: Update release number.

+;;; TODO:
+
+;; * Clean up unused *tramp/foo* buffers after a while.  (Pete Forman)
+;; * WIBNI there was an interactive command prompting for tramp
+;;   method, hostname, username and filename and translates the user
+;;   input into the correct filename syntax (depending on the Emacs
+;;   flavor) (Reiner Steib)
+;; * Let the user edit the connection properties interactively.
+;;   Something like `gnus-server-edit-server' in Gnus' *Server* buffer.
+;; * It's just that when I come to Customize `tramp-default-user-alist'
+;;   I'm presented with a mismatch and raw lisp for a value.  It is my
+;;   understanding that a variable declared with defcustom is a User
+;;   Option and should not be modified by the code.  add-to-list is
+;;   called in several places. One way to handle that is to have a new
+;;   ordinary variable that gets its initial value from
+;;   tramp-default-user-alist and then is added to. (Pete Forman)
