git annex rmurl [file url ..]
Record that the file is no longer available at the url.
Removing the last url will make git-annex no longer treat content as being present in the web special remote.
Enables batch mode, in which lines are read from stdin. Each line should contain the file, and the url to remove from that file, separated by a single space.
Makes the --batch input be delimited by nulls instead of the usual newlines.
