[Jed-users-l] extended backup (versioning)?

[Ulli Horlacher <framstag@xxxxxxxxxxxxxxxxxxxx>]

JED's backup files~ saved me often :-)

Being an old VMS hacker, I really like it's integrated versioning. Example:

file.txt;1
file.txt;2
file.txt;3

(the bigger the number, the older the file)

How about extending JED's backup file concept to a similar versioning
system for UNIX? I think of this kind of naming:

file.txt
file.txt~1
file.txt~2
file.txt~3

When one saves a new file.txt then JED should rename the old files:

file.txt~3 --> file.txt~4
file.txt~2 --> file.txt~3
file.txt~1 --> file.txt~2
file.txt   --> file.txt~1


A JED config variable would define the maximum number of backup versions.
