The latest version of Subversion is in alpha, and a list of new commands are in testing. I've added a list of some of those currently in testing so that you can familiarize yourself with them. Note that as the product is in alpha this will be a growing list as I believe there is a "wishlist" system going on.
Used after another repository user has set svn blame. Indicates that the user acknowledges the fault and is very sorry.
Used either after an svn blame function or to show disaffection with version control. The flag essentially shows that the use of Subversion in general is causing them distress.
Used to either stop the above two commands or to stop arguments regarding changes to a committed file.
Turns the svn client into a simple FTP program, bypassing the version control system.
Flag to show that the user has an ideology they wish to express. Allowed flags are -che, -stalin, -marx, -lenin, or -lolcats
svn tor -rent
Turns the subversion client into an anonymous Torrent client and hides the resultant .iso files in the repository. If used in conjunction with svn blame, then the IP address of another user is stored so the RIAA will seek legal action against the other user.
Marks that changes made by another user look weird.
Immediately makes a file live, sucking the entirety of the company bandwidth to do so, and bypasses the sysadmin.
Sends a request to the sysadmin for a tag and release, attaching a lolPicard to the email with the -caption attatched. The default caption is "wtf is this shit?"
svn fu man chu
The file is deleted, but the world shall here from it again.
