Err, no. "git merge --squash foo" merges all changes from the merge base of HEAD and foo up to foo. "git cherry-pick foo" takes just the changes from foo^ to foo. For example:

A---B---C (master)
 \
  D---E---F (foo)

git cherry-pick foo # Tries to create a new commit with the changes from
                    # "git diff D F"

git merge --squash foo # Tries to create a new commit with the changes
                       # from "git diff A F"
