Meanwhile I have written the helper program jv (jed versions) for easier
access to the file versions:

framstag@fex:/sw/share/jedlib-0.99-19/lib: jv -h
usage: jv [-l] [file]
   or: jv -r version-number file [new-file]
   or: jv -d version-number file
options: -l   list available versions
         -r   recover file
         -d   show diff
examples: jv -l project.pl
          jv -r 2 project.pl project_2.pl

framstag@fex:/sw/share/jedlib-0.99-19/lib: jv
 8 defaults.sl
 4 jed.rc
 1 misc.sl
 3 keys.sl
10 versions.sl
 1 backups.sl

framstag@fex:/sw/share/jedlib-0.99-19/lib: jv -l jed.rc

jed.rc:
#0 2013-04-13 09:02:56        13171 B (current version)
#1 2013-04-12 09:29:20        13162 B
#2 2013-04-12 09:25:19        13163 B
#3 2012-04-06 16:06:49        13074 B
#4 2012-04-06 16:03:54        13038 B

framstag@fex:/sw/share/jedlib-0.99-19/lib: jv -r 2 jed.rc
`jed.rc' -> `./.versions/jed.rc~0~'
`./.versions/jed.rc~2~' -> `jed.rc'
