del /w [minor documentation fix]

Feb 23, 2012
The documentation for DEL, in the general discussion, notes: "If you wish to obliterate a file or wipe its contents clean, use the /W option, which overwrites the file with zeros before deleting it"
However, later on, when discussing the /W option, the documentation notes that this uses the DoD 5220.22-M (E) standard to overwrite every byte in the file with a different value.
In a quick test I observe that the latter claim is correct - that is, after I deleted a file with /W it was not overwritten with zeros, but rather with a repeated series of values (in my case the values were: "DC 4E 65 D3 66 F9 CC 01").
