Warn against file wiping shortcomings
Originally created by Tails on #5831 (Redmine)
Our current secure deletion documentation does not mention simply wiping a file might not be enough. It probably should.
E.g. "deleted" copies of a file (e.g. with OpenOffice.org). The nautilus-wipe doc probably has more examples about it.
