The Subversion 1.7 release notes say: http://subversion.apache.org/docs/release-notes/1.7.html#windows-case-change
> Changing case of file and directory names on Windows > > Subversion on Windows now fully supports changing the case of file and > directory names. No more special workarounds, a simple 'svn mv file.java > File.java' just does the right thing. Is this fix really Windows-specific, or is this also now fixed on OS X and other systems with case-insensitive filesystems?
