Mmmm... close, but not exactly. As we've already seen in this thread and
previous ones, the "apparent meaning" differed from subcommand to
subcommand, from user to user, from need to need. It is absolutely the case
that long ago, we solidified the syntax into something that meant the same
thing every single time you used it. That had the effect of changing the
meaning of some invocations in incompatible ways, and we acknowledged that.
 But that was years ago, and the adoption of Subversion has vastly
flourished since then. It would be foolish to punish now *many* more users
*again* for such a change. You only hear about it when users get it wrong,
yes? If we estimate that there are something like 2 - 3 million Subversion
users, what percentage of those appear (from our admittedly limited
perspective) to be suffering from this syntax today?
