title: ankhsvn: repository gotten folded internally
body: <p>I've been using AnkhSVN with VS2010 for development of several projects ("solutions").  For a while my commits have been going fine.  But recently, Ankhsvn has changed my repository to one of my projects, so that what should be a child project now duplicates the entire repository structure.  This has happened on more that one occasion such that the current project I have to check out is located within another project which itself is within another project.  I've gone to File -> Subversion -> Change Source Control but the URL can't be edited.  When I try using Pending Changes, I get an errmsg about a broken lock on the working copy.  Of course I have tried Clean several times.  I also tried Switch which I think got me into more trouble.  How did the repo get changed in the first place?  Any idea what I did wrong (and how to fix) ? </p>
