Subject: [PATCH] Remove the helper function for "openRecursively()"

The support function for this method was unnecessary, so I took the
time to remove it. Since "TreeDirNode.openRecursively()" now calls
the "open()" method, it can take advantage of the improvements made
to that function in recent commits. Specifically, this method will
reflect the bugfix provided in pull request #720.
