I tried to run your 'git log' and 'git log .' example and a diff revealed that the output of those two isn't the same, contrary to what I thought. In the 'git-log .' case, there should be done a history simplification, but then only commits which don't change anything are pruned and AFAIR 'git commit' doesn't allow this. Using core git, one could create commits with the same tree as their parent, but I don't think that all the commits which get removed in the '.' case where produced that way. There has to be another case I can't figure out.
