[PATCH v7 0/4] MR9112: XCOPY and COPY should not attempt to copy a file to itself.

[Joe Souza (＠JoeS209)]

Current code attempts to copy a file to itself.  File is not actually copied; instead, a file sharing error is received.  This result is ugly and differs from native.  Behavior now appears to be the same as native with changes in this MR .
