You can use filter-branch to do it automatically. Something like:

  export BAD_EMAIL='The Wrong Email in Your Commits'
  export GOOD_NAME='Your Correct Name'
  export GOOD_EMAIL='Your Correct Email'
  git filter-branch --env-filter '
    if test "$GIT_COMMITTER_EMAIL" = "$BAD_EMAIL"; then
      GIT_COMMITTER_NAME=$GOOD_NAME
      GIT_COMMITTER_EMAIL=$GOOD_EMAIL
    fi
    if test "$GIT_AUTHOR_EMAIL" = "$BAD_EMAIL"; then
      GIT_AUTHOR_NAME=$GOOD_NAME
      GIT_AUTHOR_EMAIL=$GOOD_EMAIL
    fi
  '

which will rewrite just the commits with the problem. Note that this will rewrite the history of those commits. If you've shared the old ones with others, they will see them as entirely new commits instead of replacements.

Try "git rebase -i commit1".

Git doesn't currently support restartable clone. It's something that would be nice to have, but there are some technical issues that make it more difficult than simply starting where we left off (namely that the pack that is being downloaded via the git protocol is generated on the fly). You can find some previous discussions by searching the list for "restartable clone".
