using is not part of Cygwin, it's from CollabNet.  The SVN version that claims to represent
is 1.5.7, which is the SVN version that my Subversive connector claims to represent.  That
tells me that I shouldn't be having a problem.  I guess I'll have to try again and see what
happens.  Perhaps it's not a problem with SVN version mismatches.  I'll have to test this
very carefully so I don't screw up my main workspace.  I guess I'll have to create another
one just for this test.

The problem is that Subversive includes a bastardized version of what
used to be called JavaSvn and that only reads/writes the SVN 1.4
working copy format.  Change Subversive so that it is using JavaHL or
the newer SVNKit and the problems will go away.  I would update the
command line client and the Subversive connector so that it is using
the latest SVN 1.6.x version available.

Subclipse does not have this problem as it only uses JavaHL, which is
part of Subversion, or SVNKit.
