I decided to use neutronscott's solution, which I understand except the effect of these two expressions:

Code:
sed 's/[^[]*[[]\([^]]*\)]\([[][^]]*]\)*\([^]]*\)$/\1 -- \3/g' infile
            ^^^            ^^^

A group which consists of a single square bracket? I would have written the single square bracket without the enclosure but this does not work obviously.
