actually, there is a simple way to do that. Simply start from the big
commit, then

# git reset --soft HEAD^
# git reset

Then do 7 iterations of:

# git add -p

Adding or not relevant hunks for the current change to be committed,
eventually manually editing them if two or more change end up being
mangled together.
