find: do not silently disable -L when -delete is used

First of all, current behavior is not documented and confusing,
and it can be very dangerous in the following sequence:
find -L . -type l
find -L . -type l -delete
(the second line is even suggested by find(1)).

Instead simply refuse to proceed when -L and -delete are both used.
A descriptive error message is provided.
The following command can be safely used to remove broken links:
find -L . -type l -print0 | xargs rm -0

To do:		update find(1)
