You both have good points. I sort of tend to side with your argument from convenience point of view, if only because that resembles the way how people traditionally arrange incremental backups "a full dump on Sunday night, and every day incremental relative to the last full dump". Dscho's suggestion is akin to "a full dump on Sunday night, and every day incremental relative to the previous day". Both form obviously can recreate the same contents, but often "incremental since the last full synchronization point", even though it may make bigger dumps, is easier to handle for humans.

Now I see you are improving ;-)

If $IFS is set to LF, "$*" will be $1, $2, $3 concatenated with LF in between. The first character in $IFS is used for that purpose..
