The usual rule of thumb is not to modify (e.g rebase) published commits. So it's perfectly fine to adjust local commits before they go into centralized repo - from the point of view of an external observer the history is never destructively modified. This rule can be extended to topic branches or user owned branches with the caveat that others should not base their work upon the topic branch. Also remember git push --force-with-lease!
