Log Message:
Update rdiff-backup from 0.12.3 to 0.12.4:

New in v0.12.4 (2003/09/13)
---------------------------

Specified socket type as SOCK_STREAM.  (Error reported by Erik
Forsberg.)

Fixed bug backing up unreadable regular files and directories when
rdiff-backup is run by root on the source site and non-root on the
destination side.  (Reported by Troels Arvin and Arkadiusz
Miskiewicz.)

If there is data missing from the destination dir (for instance if a
user mistakenly deletes it), only warn when restoring, instead of
exiting with error.

Fixed problems with --restrict options that would cause proper
sessions to fail.  Thanks to Randall Nortman for error report.

File examples.html added to distribution; examples section removed
from man page.
