Hi,

Attached is a patch that adds support for spaces in filenames or paths for
CLI commands such as restore, by supporting quotes. E.g:

restore "path with spaces/test.x" 

2008-12-02 Jon Beniston <jon@beniston.com>

        * cli/cli-dump.c: (scan_filename_with_cleanup) Add support for
quoted 
        strings to allow spaces in paths and filenames.

Cheers,
Jon
