(server-switch-buffer): Handle the case where all windows are
dedicated or minibuffers.

(gamegrid-setup-default-font): Ported the code from XEmacs to
Emacs: create a new face and assign the variable `gamegrid-face'
to it. Make sure that the face is not higher than the smallest
image used by the game.
(gamegrid-initialize-display): Use `(setq cursor-type nil)'
instead of `gamegrid-hide-cursor'.
(gamegrid-set-face): If `gamegrid-display-mode' is 'glyph, put an
image in the buffer, instead of applying a face.
(gamegrid-init-buffer): If `gamegrid-display-mode' is 'glyph, put
the face held by `gamegrid-face' in an overlay over the whole

"ftp".
From Michael Albinus <Michael.Albinus@alcatel.de>.

Version 2.0.20 released.
2002-09-20 Kai Gro�ohann <grossjoh@ls6.informatik.uni-dortmund.de>
* net/tramp.el (tramp-completion-function-alist): Escape open

takes USER and HOST arguments, to be able to use
`tramp-find-method'. Update callers.
(tramp-find-method): New function.
2002-09-20 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-handle-insert-directory): Handle "--dired"
in SWITCHES (by removing it).
2002-09-18 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-file-name-handler): Add `file-remote-p'
property.
2002-09-17 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (top-level): Maybe autoload uudecode-decode-region.
2002-09-16 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-bug): Add tramp-methods.
2002-09-16 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>

tramp-encoding-function and tramp-decoding-function are not
parameters anymore.
(tramp-uuencode-region): Autoload it.
2002-09-13 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
Version 2.0.19 released.
* net/tramp-uu.el: New file, implements uuencode in Lisp.
* net/tramp.el (tramp-coding-commands): Use
`tramp-uuencode-region' as local encoder for the uuencode based
entries.
2002-09-13 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-handle-write-region): Wrong parens.
2002-09-13 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
Version 2.0.18 released.
* net/tramp.el (tramp-perl-decode): Perl changes to accomodate
older versions of Perl. Now tested with 5.004. Suggestion from
Michael Albinus.
2002-09-12 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-find-inline-encoding): Call
tramp-call-local-coding-command with nil for INPUT and OUTPUT.
(tramp-call-local-coding-command): OUTPUT equals nil means to
discard the output. INPUT equals nil means /dev/null.
2002-09-12 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-encoding-shell): Default to environment
variable COMSPEC on Windows.
(tramp-handle-write-region): More debugging output.
(tramp-find-inline-encoding): Ditto.
2002-09-11 Michael Albinus <Michael.Albinus@alcatel.de>
* net/tramp.el (tramp-completion-handle-file-name-all-completions):
Define `result1'.
(tramp-parse-hosts-group): Discard IPv6 entries.
2002-09-11 Kai Gro�ohann <grossjoh@ls6.informatik.uni-dortmund.de>
* net/tramp.el (tramp-post-connection): Only send Perl
mime-encode/decode implementations when using inline method.
(tramp-handle-file-local-copy)
(tramp-handle-write-region, tramp-post-connection)
(tramp-coding-commands, tramp-find-inline-encoding): For the
inline encodings, distinguish between local and remote commands,
instead of between commands and functions. (The local commands
can be functions, too.) If the local host is a Windows machine,
we can't expect the same commands to work there as on the remote
host.
(tramp-call-local-coding-command): New function for calling local
encoding and decoding commands.
(tramp-set-remote-encoding, tramp-get-remote-encoding)
(tramp-set-remote-decoding, tramp-get-remote-decoding)
(tramp-set-local-encoding, tramp-get-local-encoding)
(tramp-set-local-decoding, tramp-get-local-decoding): New
functions.

functions, removed.
2002-09-10 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-open-connection-setup-interactive-shell):
Change command to invoke /bin/sh slightly to make it compatible
with the `rc' shell. Suggested by Daniel Pittman.
2002-09-10 Michael Albinus <Michael.Albinus@alcatel.de>
* net/tramp.el (tramp-handle-write-region): Added missing
`)'. Hope it's the right place.
2002-09-09 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-open-connection-setup-interactive-shell): Do
"exec env PS1='$ ' /bin/sh" instead of just "exec /bin/sh" in
order to get a sane shell prompt. If people have ${CWD}, say, in
their shell prompt, then the default login shell might display
something harmless, but the /bin/sh will display a dollar sign
which confused the subsequent prompt recognition.
(tramp-multi-action-password): More debugging output.
(tramp-encoding-shell): Renamed from tramp-sh-program. More
documentation. Default to cmd.exe on Windows NT.
(tramp-encoding-command-switch): New variable. Use instead of
hard-wired "-c" which is only good for /bin/sh.
(tramp-encoding-reads-stdin): New variable. If t, commands are
called like "/bin/sh -c COMMAND <INPUT", if nil, they are called
like "/bin/sh -c COMMAND INPUT", ie the input file is the last
argument.
(tramp-multi-sh-program): Always default to tramp-encoding-shell.
(tramp-handle-file-local-copy, tramp-handle-write-region): Respect
tramp-encoding-shell and friends.
(tramp-find-inline-encoding): Use new-style calls for checking if
the local commands work.
2002-09-07 Michael Albinus <Michael.Albinus@alcatel.de>
* net/tramp.el (tramp-methods): Remove `tramp-completion-function'
entries. They are handled now by
`tramp-completion-function-alist'.
(tramp-completion-function): Defvar removed. I've never used
it. Hmm.
(tramp-get-completion-function)
(tramp-get-completion-rsh, tramp-get-completion-ssh)
(tramp-get-completion-telnet, tramp-get-completion-su): Functions
removed as well. Not necessary any longer due to extended
customization means.
(tramp-completion-function-alist): New defcustom. Holds all
FUNCTION FILE pairs used for user and host name completion
relevant for METHOD.
(tramp-completion-function-alist-rsh)
(tramp-completion-function-alist-ssh)
(tramp-completion-function-alist-telnet)
(tramp-completion-function-alist-su): Defconst for initializing
`tramp-completion-function-alist'. Unfortunately, mainly UNIX-like
values are known for me until now. Needs to be completed for at
least VMS++ like operating systems.
(tramp-set-completion-function)
(tramp-get-completion-function): New functions for configuration
of `tramp-completion-function-alist'. The old definition of
`tramp-get-completion-function' has been discarded.
(tramp-completion-handle-file-name-all-completions): Change
function call for user/host completion according to definition in
`tramp-completion-function-alist'.
(tramp-parse-passwd): Added exception handling for "root", because
`tramp-get-completion-su' (the previous place for this stuff)
doesn't exist any longer.
2002-09-07 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-enter-password): Use
`tramp-password-end-of-line' to terminate the line.
(tramp-bug): Include new variable `tramp-password-end-of-line'.
(tramp-password-end-of-line): New variable. People who use plink
under Windows might have to issue "\r\n" after the password, but
they need to send just "\n" after the other commands. So this
variable was introduced to complement `tramp-rsh-end-of-line'.
(tramp-wait-for-output, tramp-post-connection): Allow "\r" at end
of line of the output delimiter.
2002-09-06 Kai Gro�ohann <Kai.Grossjohann@CS.Uni-Dortmund.DE>
* net/tramp.el (tramp-handle-file-local-copy, tramp-find-shell)
(tramp-open-connection-setup-interactive-shell): Add some comments
about Douglas Grey Stephen's suggestions to make Tramp work better
with plink under Windows. I'm not sure what to think of them, but
now I have a guinea pig to try it out on. Said guinea pig is
having other problems, though... Also remove some commented-out
code.
2002-09-06 Michael Albinus <Michael.Albinus@alcatel.de>
* net/tramp.el (tramp-get-completion-methods): Algorithm slightly
tuned.
(tramp-get-completion-user-host): Accept user names as they are if
typed until "@".
(tramp-completion-mode): Replace `last-input-char' by modern
`last-input-event'. Check for `event-modifiers'.

* net/tramp.el (file-expand-wildcards): Corrected check to see if
advising is necessary.

(tramp-make-multi-tramp-file-format-separate): Removed.
(tramp-make-tramp-file-name): Allow partial tramp file
names. Generate tramp file format on-the-fly depending on
parameters. Apply atomar format strings resp expressions.

`tramp-make-tramp-file-name'.
(tramp-parse-hosts-group): Take all host names and IP addresses
into account.
