Bug 3319 Followup: Fix compatibility with fix for bug 4945

The fix for 3319 overwrote the @branchloop variable with output from GetBranchesLoop,
which forces a selected branch.  Removing the extra call, and just measuring the size of
@branchloop as it was build, plus some dereferencing, fixes the issue.
