CP enhancement

[Thomas Kimpton]

"cp -n srcFile destFile" returns 0 if it copies the file. It also returns 0
if it fails to copy the file over an existing file. I would like "cp -n" to
return 1 (or perhaps EEXIST) when it will refuse to overwrite an existing
file. This would facilitate:

     cp -n srcFile destFile && chmod +x destFile

Or other similar idioms.

Thanks!
