These errors are mostly fixed by either adding blank lines or single
spaces for Sphinx documentation key words.

The commit solely includes documentation changes, no functional
changes.

When passing the "message" kwarg, this would add a -m command-line flag
without removing --message, and the message would be duplicated. Avoid
that by deleting "message" from the command line.

This reverts commit 53d94b8091b36847bb9e495c76bb5a3ec2a2fdb5.

The reason for the revert is that the commit in question introduced a
regression where certain modules, functions and classes that were
exposed before were no longer exposed.

See https://github.com/gitpython-developers/GitPython/pull/1352#issuecomment-932757204
for additional information.

All `from <module> import *` has now been replaced by
`from <module> import X, Y, ...`.
