The code herein changes commit timestamp recording from a source in a
more intuitive way.
Description:
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.
In the first case timestamp should by default be taken by the time we
are doing the commit, not by the source. On the second case the actual
behavior is acceptable.
Anyway this update creates new options for choosing the source timestamp
or a new one. And set as default for -c option (editing one) to take a
new timestamp and for -C option the source timestamp. That is because
we are normally using the source as template when we we are editing and
as a correction when we are just copying it.
Those options are also useful for --amend option which is by default
behaving the same.
