The previous commit introduced --ignore-date flag to interactive
rebase, but the name is actually very vague in context of rebase -i

This sounds more like the existing "--reset-author" but only takes
over the timestamp part without taking over the authorship.
IOW, I am wondering if "--reset-author-date" is a better name.
