Could rdiff-backup at least get a --progress option, similar to rsync,
that gives an indication of how far the processing is? At the moment
the main options seem to be:

1) Run in regular non-verbose mode, and don't see much of anything.
For all we know, it has frozen.

2) Run with more verbosity. The messages aren't very intelligible or
useful for end-users, a lot of the time.

It would be great to get a display, something like this, when the user
runs rdiff-backup with --progress:

- Listing files (1000)... <- This number goes up as the files are listed
- Processing files (500/1000, 50%, eta: 10:13:12) <- Progress updates
as files are processed.

Could something like the above be added to rdiff-backup? That way we
can get an idea of how fast it's running, when it will complete, or if
it has frozen.
