        A log is a history and a history is not at state nor a collection
        of states. Humor me for a moment...

        If we were talking about "svn info", "svn update", or other
        "state" tools I'd agree. But we're talking about "svn log" which
        is a history tool. -As I noted in another post, if it was a
        state tool it couldn't accept ranges like -r10:20 much like svn
        info can not.

        But I think it matters not. I'm of the mind now that the way to
        move forward is not to mess with the current results svn log
        produces (no matter what I think of them), but instead to expand
        the svn log command to offer a new syntax for such things:

                svn log -r10:20 path@ALL

                Results in the history of path between revs 10 and 20
                inclusive, irregardless of peg version changes or

                svn log --action A path@ALL

                Results in all log entries where path was Added,
                regardless of the peg versions.

                svn log --action D path@1234

                Results in the single log entry which notes path being
                deleted (or replaced) for peg version (ie object) 1234.
                To match current SVN nomenclature 1234 must be a rev
                of the object at a state when it did exist. In the
                above example it might return the log for r4567 if that
                was the log which describes the Deletion of 1234.

                svn log path@ALL

                The entire history of path from the first Add to the
                last Deletion and everything in between, irregardless
                of the peg version or the existence of a peg version.
                In other words "ALL" really, truly, means "ALL,
                Everything, Give it to me I can handle it baby, yah!"

        I'm starting to work on coding this up in svn to see how well
        it might function in practice.
