Hello,
In fileutils-4.1, if a file is listed twice in the source list, cp
copies the file twice, overwriting the first copy. In
fileutils-4.1.1, cp generates an error, even if the -f flag has been
specified:
in fileutils-4.1.1:
$ touch baz
$ mkdir blurfl
$ /usr/local/bin/cp --version
cp (fileutils) 4.1.1

$ /usr/local/bin/cp baz baz blurfl

$ /usr/local/bin/cp -f baz baz blurfl

$ /bin/cp --version

$ echo $?

I did not find this change mentioned in the NEWS file. This change
will likely break some scripts and makefiles which utilize the old
'feature'; I discovered it when building the XEmacs packages
hierarchy, which contains makefiles which (admittedly sloppily) use
macros to supply overlapping lists of source files for cp to copy.

Vin Shelton
