* tramp.el: Version 2.0.31 released.

(tramp-handle-expand-file-name): Do not allow ".." to
cross file handler boundaries, so that "/user@host:/../foo"
expands to itself, rather than "/foo".  This is intended to work
in conjunction with a change in `file-relative-name' which makes
sure to use absolute file names if FILE and DIRECTORY have
different handlers.
(tramp-handle-insert-directory): Comment out XEmacs
kludge.  Suggested by Katsumi Yamaoka <yamaoka@jpl.org>.

* Makefile.in (../info/tramp): Compile Emacs, instead of XEmacs,
version of manual.

* tramp.texi (Auto-save and Backup): New node.

+
+By default, @command{make install} will install @tramp{}'s files in

+installation prefix other than @file{@value{prefix}} by giving
+@command{configure} the option @command{--prefix=PATH}.
+
+If your installed copy of Emacs is named something other than
+@command{@value{emacs-dir}}, you will need to tell `make' where to find it so
+that it can correctly byte-compile the @tramp{} sources.
+
+For example, to force the use of @value{emacs-other-name} you might do
+this:
+
+@example
+./configure --with-@value{emacs-other-dir}
+make
+make install
+@end example
+
+or this:
+
+@example
+./configure
+make EMACS=/usr/bin/@value{emacs-other-dir}-21.4
+make install
+@end example
+
+The syntax of @tramp{} file names is different for @value{emacs-name}
+and @value{emacs-other-name}.  The Info manual will be generated for
+the Emacs flavor choosen in the @command{configure} phase. If you want
+the Info manual for the other version, you need to set the variable
+@command{EMACS_INFO} to @command{make}:
+
+@example
+./configure --with-@value{emacs-dir}
+make EMACS_INFO=@value{emacs-other-dir}
+@end example
+
+Also, the @command{--prefix=PATH} option to @command{configure} may
+not be general enough to set the paths you want.  If not, you can pass
+variables to the @command{make} command to control the installation.
+For a complete list of tweakable variables, look in the makefile.
+
+For example, to put the Lisp files in @file{~/elisp} and the Info file

+Explaining auto-save is still to do.
+
+Normally, Emacs writes backup files to the same directory as the
+original files, but this behavior can be changed via the variable
+@code{backup-directory-alist}.  In connection with @tramp{}, this can
+have unexpected side effects.  Suppose that you specify that all backups
+should go to the directory @file{~/.emacs.d/backups/}, and then you edit
+the file @file{/su:root@@localhost:/etc/secretfile}.  The effect is that
+the backup file will be owned by you and not by root, thus possibly
+enabling others to see it even if they were not intended to see it.
+
+When @code{backup-directory-alist} is nil (the default), such problems
+do not occur.
+
+If you wish to customize the variable, the workaround is to include
+special settings for Tramp files.  For example, the following statement
+effectively `turns off' the effect of @code{backup-directory-alist} for
+@tramp{} files:
+
