My users disliked the versions~ mess in the regular directory, so I moved
them to a .versions/ subdirectory.
Then the vi users requested the same function :-}
So I wrote the helper script vv (visual versioning):

http://fex.rus.uni-stuttgart.de/fstools/vv.html

usage: vv [-l] [file]
       vv -r version-number file [new-file]
       vv -d version-number[:version-number] file
       vv -v version-number file
       vv -s file
       vv -e file
       vv -p
       vv -m [-R]
       vv -I
options: -l   list available versions
         -v   view version
         -r   recover file
         -d   show diff
         -s   save file to new version
         -e   edit file with $EDITOR (with versioning)
         -p   purge orphaned versions (without current file)
         -m   migrate backup files to version files (-R all recursive)
         -I   show more information
examples: vv -l project.pl
          vv -d 2 project.pl
          vv -r 2 project.pl project_2.pl


vv can be integrated into jed if you use vv.sl
http://fex.rus.uni-stuttgart.de/sw/share/jedlib/vv.sl


Now jed makes a backup of every file, even new ones. Example:

framstag@fex:/tmp: jed newfile
(edit and save)
framstag@fex:/tmp: rm newfile
framstag@fex:/tmp: vv newfile
vv: newfile does not exist any more
found ./.versions/newfile - recover it? y
`./.versions/newfile' -> `newfile'
