I think the only reason not to bump the marker forward during the push would be if the helper wants for some reason to "re-import" from the foreign source rather than accepting the git versions of the commits. Something like git-svn's markup of the commit messages with revision ids comes to mind. But if it matters, then by definition that would mean that the import/export is not bidirectionally clean. git-svn is definitely not that, but I hope that vcs-svn will be (I have not kept up on its status). So I can buy the argument that bumping it forward ourselves will not matter for any well-implemented helper. That is the sort of thing that might be helpful to include in the commit message; if somebody does run across such a helper and bisects to your commit, then they can understand the rationale for the decision. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
