[patch] /bin/cp POSIX conformance

[Jason Smethers]

IEEE Std 1003.1-2004 also states the following for the cp utility under 
section 2e:

2. If source_file is of type directory, the following steps shall be taken:

. ..

  e. ... If dest_file cannot be created, cp shall write a diagnostic 
message to standard error, do nothing more with source_file, and go on 
to any remaining files. ...



Currently the cp utility exits with the error message. An updated 
inclusive patch is listed below.
