I had been more thinking of a process that passed single sha1's to the 
filter on each pass through the rebase list, so that the coding was simpler, 
plus the --interactive could be used, if required, for final refinement 
(gitk being handy for that).

However, a mention in the man pages would be zero code cost, and could help.
