I've added three new functions to the ikiwiki VCS interface to support renaming and removing files using the web interface. The mercurial and tla [[rcs]] backends need implementions of these functions. (The maintainers of these backends have been mailed. --[[Joey]]) Also, currently git is the only VCS to have support for [[untrusted_push|tips/untrusted_git_push]]. It _may_ be possible to implement it for other DVCS, if they offer a hook that can be used to check incoming pushes early.
