Currently, when you move/rename a file/directory using TortoiseHg and hgSubversion, one delete and one add will be performed. This breaks the svn history of a file/directory.
I would like to see support for the 'svn move' command as described here: http://svnbook.red-bean.com/en/1.7/svn.ref.svn.c.move.html
This would allow moving and renaming files with TortoiseHg + hgSubversion while preserving their full SVN history.
My current workaround is to use the TortoiseSVN Repo-Browser for move/renames, but this is of course very inconvenient.
