Well it seems to me that with some scripts this can be achieved
easily, ie

  git show COMMIT:README

gives the blob, and

  git show --no-patch [--pretty=XY] COMMIT

gives the commit object (to the given extend), which can then be
parsed and used for example to fill in the environment variables

       GIT_AUTHOR_NAME
       GIT_AUTHOR_EMAIL
       GIT_AUTHOR_DATE
       GIT_COMMITTER_NAME
       GIT_COMMITTER_EMAIL
       GIT_COMMITTER_DATE

for "git commit" accordingly.  There you go.

All in return.
