[Bug-tar] tar-1.14 'backup' and 'restore' scripts

[alexb]

Hello!

I have following problem:

I looked at 'backup' and 'restore' scripts shipped with tar-1.14 to
understand how to make incremental backup/restore properly. In 'backup'
script naming of --listed files is

${fsname}.levelN

In 'restore' script the same naming used to create list of incremental
listings (--listed files) to process. But when calling backup_host function
the following naming used:

--listed=`level_log_name $fs $level`

i.e. ${fs}.levelN

Do I misunderstand something about incremental backups?
Or is it a bug in 'restore' script?

Thank You Very Much
