Un-add a new file

What if you change your mind about adding a new file?

# If you already committed the new file

Delete it from the repository:

> svn rm _whoopsie.mistake_
> svn commit

# If you didn't commit the file but already did "svn add"

> svn revert

# If you haven't done "svn add"

Just delete it. Or leave it there for now; it's not bothering svn to have it there.
