-   		    * inserted additional |:keepj| modifiers
-		    * changed silent  to  sil!  (|:silent|)
-   v26 Aug 09, 2010 * uses buffer-local instead of window variables to hold
-		      tarfile name
-		    * inserted keepj before 0d to protect jump list
-   v25 Jun 19, 2010 * (Jan Steffens) added support for xz compression
-   v24 Apr 07, 2009 * :Untarvim command implemented
-       Sep 28, 2009 * Added lzma support
-   v22 Aug 08, 2008 * security fixes
-   v16 Jun 06, 2008 * tarfile:: used instead of tarfile: when editing files
-		      inside tarballs.  Fixes a problem with tarballs called
-		      things like c:\abc.tar. (tnx to Bill McCarthy)
-   v14 May 09, 2008 * arno caught a security bug
-       May 28, 2008 * various security improvements.  Now requires patch 299
-		      which provides the fnameescape() function
-       May 30, 2008 * allows one to view *.gz and *.bz2 files that are in
-		    *.tar files.
-   v12 Sep 07, 2007 * &shq now used if not the empty string for g:tar_shq
-   v10 May 02, 2006 * now using "redraw then echo" to show messages, instead
-		      of "echo and prompt user"
-   v9 May 02, 2006 * improved detection of masquerading as tar file
-   v8 May 02, 2006 * allows editing of files that merely masquerade as tar
-		     files
-   v7 Mar 22, 2006 * work on making tar plugin work across network
-      Mar 27, 2006 * g:tar_cmd now available for users to change the name
-		     of the tar program to be used.  By default, of course,
-		     it's "tar".
-   v6 Dec 21, 2005 * writing to files not in directories caused problems -
-		     fixed (pointed out by Christian Robinson)
-   v5 Nov 22, 2005 * report option workaround installed

-      Oct 18, 2005 * handles writing to compressed archives
-      Nov 03, 2005 * handles writing tarfiles across a network using
-		     netrw#NetWrite()
-   v2              * converted to use Vim7's new autoload feature by
-		     Bram Moolenaar
-   v1 (original)   * Michael Toren (see http://michael.toren.net/code/)
+	v31	Apr 02, 2017	* (klartext) reported that browsing encrypted
+				  files in a zip archive created unencrypted
+				  swap files.  I am applying a similar fix
+				  used on zip.vim to tar.vim: new buffers
+				  are opened with |:noswapfile|.
+		May 16, 2017	* When the mouse option isn't empty, the
+				  leftmouse can be used to select a file
+				  in the tar-file listing.
+	v30	Apr 22, 2014	* .tgz files are ambiguous: they may have been
+				  compressed with either gzip or bzip2.  Tar.vim
+				  disambiguates by using unix's "file" command.
+		Feb 18, 2016	* Changed =~ to =~# where appropriate
+		Feb 18, 2017	* Now also permits xz decompression
