ddrescue reverse mode bug

example hand start reverse without map, and go 123 and stopped, and need to 
rerun at pos 123 reverse hand.

i try example

ddrescue -i123 -o123 it normal ok posion

if try 
ddrescue -i123 -o123 -R 

it starts write at the end disk 500000 from 123 but need start in 123

if reverse -R is on loacating error it is start write in the end disk. position 
input/output 500000 but read from 123. ie shift 123 ok, but -i -o is ignored ?
