For some system locale settings dar may include all files for
incremental backup referenced to isolated catalogue and also produce
bad result for 'dar -d' command with catalogue.
I would like to save the full backup on DVD and keep the small isolated
catalogue on HDD for incremental backups. But when I try to make
incremental backup with reference to isolated catalogue I have found a
bug: dar (2.2.3) include all files. My locale is ru_RU.koi8-r.
Patch fixes this bug.
