Summary:                    tail -f should keep following files even if they
were truncated
Description: 
The current implementation of tail doesn't keep watching truncated logs: it
simply looks if anything was been added beyond the current reading
position, it does not adjust for file truncation. This patch is inspired
from Chip Rosenthal's xtail which i downloaded from
http://www.unicom.com/sw/xtail/

tail -c NNN /dev/a_block_device is fixed in rev 21058.
(wasn't broken really, just was taking ages to read entire device...)
