I imagine it is because it is a special case when a parent folder is
copied/moved. You would have to ask the Subversion devs why it is this
way. I think it is part of the O(1) algorithms behind copies.

I am not able to parse this, especially the first sentence. Probably
doesn't matter though.

Not really. There is a better API available now, TSVN must not be using
it yet in this case. With the fix I added, this should not be a problem
in Subclipse anymore.

I will just say that I respectfully disagree and think that you are
blowing this way out of proportion. These are not really bugs in
Subversion. A user of the command line would not likely run into any of
these problems. Simply because they have to think and type out a command.
 They are rarely going to type out a URL and svn log and specify anything
more than the root URL, because they do not have to. In the GUI, we are
trying to infer information from the context and avoid asking you
questions. In some cases, the API's we needed were not available to us,
in others it was just oversight by the person that implemented the feature
in not knowing all of the scenarios that can come up. With JavaHL, we
have to wait for the API to be added and generally available before we can
use it. TortoiseSVN has an advantage here. Since it is written in C++ it
can access the entire API as it needs.

In the case of blame, we already have and it will be in the next release.
The last release was the first one where we had these API's available, but
we had to mostly focus on just getting a compatible release out which
contained support for the new features, like locking.

In the case of log, we added the concept of letting you tell us the root
URL. That makes it work reliably in all situations.
