[Bug-ddrescue] Trimming blocks even though set to read 1 sector at a time

[Scott D]

First I will say that this is happening with version 1.15, so if it is 
different in the newer versions please let me know.

I am using the option -c 1 to only read 1 sector at a time. The drive 
has many bad single sectors (I think it got bumped hard during a write 
and wrote across the disk in a spiral). So I don't want to read any bad 
sectors twice as it doubles the read time and I know they will not read. 
But even reading 1 sector at a time it still wants to trim the blocks 
and performs another read of all bad sectors, which like I stated 
doubles the read time. Is there a way to prevent this?
