When I do a svn status .
, I get this:
! C auto-complete-config.elc
> local edit, incoming delete upon update
! + C auto-complete.el
So you can just revert the file that you deleted but remember, If you are working on any type of project with a set project file (like iOS), reverting the file will add it to your system folder structure but not your project file structure. additional steps may be required if you are in this case
