From ddrescue.info:
"In fill mode the input file may have any size. If it is too small,
the data will be duplicated as many times as necessary to fill the input
buffer. If it is too big, only the needed data will be read. Note that
you may specify a starting position for the input file."

The input file reading does not wrap around at EOF. There is a 
difference, because the file size may be unknown before reading it.

Oops! You are right, but I can't use the -i option to solve this because 
it is already used as (surprise) a starting position for the input file. 
Storing the offset in the logfile isn't an option either, because the 
same files can be used several times with different offsets.

Just now I can't think out any elegant solution, but this need to be 
solved soon.
