title: modify SVN change log
body: <p>I'm using VisualSVN and tortoise to work with an SVN repository.  Someone needed some folders moved from one location to a new location in the same repostiory.  I goofed up though and just copy/pasted the old folders into the new location (didn't get the change history, etc).  Since then they have updated a bunch of the files.  The old files (from the previous location) weren't deleted or anything.  Is there a way to get the change history from the old files and associate it with the new location?  I would need to add revision numbers, log messages, etc.</p>
