empty lines in /etc/crypttab

- what component?!?  If you want people to use bugzilla, please make it 
easy first.. ]

Currently, the /etc/init.d/cryptdisk script expects any non-data lines 
to be comments ('^#'). It should allow for empty lines, too:

    grep -v '^#' < $TABFILE | grep -v '^[:space:]*$' | while read dst 
src key opt; do

Without this, empty lines in '/etc/crypttab' will cause weird "missing 
parameter" output in bootup. Non-destructive, but gives the "oops, all 
is not as it should!" feeling. Anyhow, this should be fixed?
