Comment 5 for bug 483631

OK, here is a patch with just the 10.3 bugfixes (no translation/automake changes).

It does three things:
 - Allow restoring files in a read-only directory
 - Allow restoring a file from a directory that doesn't exist yet
 - Don't download all files to restore just one

The first two can manifest themselves as data loss (or at least, no easy way to get your data that is locked inside your backup). The last could make it very difficult to restore specific data if you are short on disk space (would need to use a different computer). Thus, the SRU request.

Please re-review. Thanks!
