numbered backup control

[Michael Wirtz]

Hi tar team,

I've noticed the following behaviour :

For numbered backup control I give the commandline parameter
"--backup=t". This works perfect for archive names that do not exceed 10
columns. Subsequent use of the  command "tar cf 123456.tar <file(s)>
--backup=t" produces the archives

123456.tar
123456.tar.~1~
123456.tar.~2~

and so on; this is exactly the result I expected. Subsequent use of the
command "tar cf 1234567.tar <file(s)> --backup=t" produces only two
archives :

1234567.tar and
1234567.tar~

so there is no more numbered backup version if the length of the archive
name exceeds ten columns.

I am running tar version 1.13 on Slackware 7. Am I doing anything wrong
or is it a bug ?
