shelve is (surprisingly) sensitive to working directory

While messing around with things recently, I decided to try out shelve
to save some of my pending changes. This didn't work as well as I
expected, since I wasn't in the root of my working copy. Simplified
transcript below demonstrates the issue:

[[[
jamessan_at_freya:~/src/apache.org/subversion/trunk$ svn info | grep ^Work
Working Copy Root Path: /home/jamessan/src/apache.org/subversion
jamessan_at_freya:~/src/apache.org/subversion/trunk$ ./subversion/svn/svn stat
M subversion/libsvn_client/shelve.c
jamessan_at_freya:~/src/apache.org/subversion/trunk$ ./subversion/svn/svn shelve demo
C /home/jamessan/src/apache.org/subversion/subversion/libsvn_client/shelve.c
> rejected hunk @@ -216,7 +216,6 @@
shelved 'demo'
]]]

Notice that a conflict is shown and the full path is incorrect (missing
/trunk/). It looks like the relative path from my working directory was
appended to the working copy root, which is clearly wrong.

[[[
jamessan_at_freya:~/src/apache.org/subversion/trunk$ svn stat
