How can I determine the trunk-revision used to create a branch with SharpSvn?

Question

I am currently building a ChangeLog-generator, which is creating such a log by diff'ing the revisions of /trunk against /branch/... (which was created at some point from /trunk), to see which commits are not in the branch (and then does some fancy Redmine queries).

To minimize the log-range I wanted to optimize the query based on the revision used to create the branch as my offset.

I know the Stop on copy/rename feature of TortoiseSVN, to determine the revision used to create a specific branch or tag.

How can I achieve this with SharpSvn - or is there an easier way to determine the difference (to simplify the request: I will only diff /trunk against a descending branch ...).

I got this to work with the following code - yet I am unsure if this is the most elegant way to do so:

var svnClient = new SvnClient();
svnClient.GetLog(new Uri("http://..../REPOSITORY/BRANCH/FOO",
                 new SvnLogArgs
                 {
                   StrictNodeHistory = true
                 },
                 out logItems);
var initRevision = logItems.OrderBy(arg => arg.Revision)
                           .First();
var changedPath = initRevision.ChangedPaths.Single();
//changedPath.CopyFromRevision
//changedPath.CopyFromPath

The thing that bugs me, is that I have to get the whole log, then order it accordingly to get the initial revision, which is used to retrieve the CopyFromRevision and CopyFromPath properties.
