[ast-developers] Documentation clean-up for the AST cp command

[Terrence J. Doyle]

I noticed a word omission when I typed "cp --?". The -P (or -d)
option states:

-P|d, --physical|nodereference
Don't follow symbolic links; copy symbolic rather than the
files they point to.

I figure it would read better like this:

-P|d, --physical|nodereference
Don't follow symbolic links; copy symbolic links
rather than
the files they point to.

I've attached cp.c.diff to update the getopts documentation for cp.
