"svn status -u" and svn:externals - bug?

Hi SVN users,

I searched for this problem in the open issues but could not find a similar problem.
Can you help me to find out if this is a known problem/bug?

I have a repository with a few svn:externals. Some of them point to a specific revision (e.g. trunk_at_8) of their repository.
When I look up with "svn status -u" if I have to do an update SVN shows me files out of this external repositories which should be reputedly newer on the server.
The problem is that the external repository has newer revisions with a newer version of this file but this should not play a role for my repository (because of the trunk_at_8).

Example extract of the console output:
C:\WORKSPACE\SVN>svn propget svn:externals
file://???/SW/trunk_at_8 SW

C:\WORKSPACE\SVN>svn status -u
Status against revision: 117

Performing status on external item at 'SW':
        * 8 C:\WORKSPACE\SVN\SW\Code.c
Status against revision: 13

I looked in the source code and tried to find the reason for this behaviour.
I think that the problem is in status-cmd.c svn_cl__status().
There I found this piece of code which may cause this problem:
  /* We want our -u statuses to be against HEAD. */
  rev.kind = svn_opt_revision_head;
In my opinion in the case of external repository with fixed revision the check should be performed against this revision?

A similar problem exists if I do an update on a subfolder (one which is added by svn:externals and points to a specific revision) of my repository then the HEAD revision of this folder is checked out.

If needed I can try to do a repro-template.bat.
Normally I work with TortoiseSVN and SVN Notifier but because of the problem I tried to reproduce it on the command line.

Windows 7 - Subversion 1.7.9
