AH HA! Got it now. Thank you.

It does indeed. Unfortunately it brings me back to a variation on my original
bug report (which was wrong):

$ svn mkdir A; svn commit -m ""
$ svn mv A B; svn commit -m ""
$ svn mkdir A; svn commit -m ""
$ touch A/versionedfile; svn add A/versionedfile; svn commit -m ""
$ svn mv A B; svn commit -m ""

The second case fails with:
Deleting A
svn: Commit failed (details follow):
svn: Out of date: 'A' in transaction '3'

It can be made to complete however, with:
$ svn status
D A/versionedfile
A + B
$ svn update
At revision 2.
$ svn status
D A/versionedfile
A + B
$ svn commit -m ""

There is no difference between the two "svn status" outputs. "svn update"
reported no changes. Yet, after "svn update" the A directory is gone (good)
and so the svn commit can complete.

My bug report/feature request is therefore: whatever "svn update" is doing
(which in this case is not its stated function of bringing the local copy up
to date with the repository); can "svn mv"/"svn rm" not do that as well?

This only shows up for directories. Files behave as expected "svn mv A B"
when A and B are files, leaves the local copy with no A.
