Even if there were no problems, it's not very nice. It uses an additional
repository which is quite strange. Moreover, there's no way to find out how the
saved working tree snapshot is related to existing ordinal commits.

Try using low-level git commands (the "plumbing").
Take a look at GIT_INDEX_FILE environment variable and
"git write-tree", "git commit-tree" and "git update-ref", in
addition to "git add".

I.e. (untested):

  $ (
  export GIT_INDEX_FILE=.git/myindex
  git add . &&
  tree=$(git write-tree) &&
  commit=$(date |git commit-tree $tree -p protocol) &&
  git update-ref -m autolog protocol $commit
  )
