I think I understood the idea behind TAG_FIXUP and I think it can be a
better solution for my problem. I could make the commit into
TAG_FIXUP, search for a better parent in the source branch and then
reset it to that parent or rebase it over any other commit. I'll try
to do this in the following days, so I will most likely come back with
more doubts :)
