edittemplate patch from Willu

[ikiwiki] / doc / todo / rcs_updates_needed_for_rename_and_remove.mdwn

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]])
