problem is, with the current implementation by listing all files you cannot 
distinguish different versions in the listings.

you can list all files for one date/time currently. to get all versions from 
all times you have to repeat this and filter the output to get the list you 
want. not performant but possible.

right, raise verbosity until you get the entries of files added/changed/etc

correct, you can use absolute and relative times, check manpage for the syntax

eventually, although currently not implemented as you want, it is definitely 
possibly to add this to duplicity. if you want to dive into python or want to 
sponsor it you could so.
