When we use one of the options above we are normally trying to do mainly
two things: one is using the source as a template and second is to
recreate a commit with corrections.
When they are used, the authorship and timestamp recorded in the newly
created commit is always taken from the original commit. And they
should not when we are using it as a template.
The new --mine option is meant to solve this need by regenerating the
timestamp and setting as new author the committer or the one specified
on --author option.
