Allow partition dynamically allocated by --largest-new to be referenced by other options

The documentation for the option --new explains that:

> [a] partnum value of 0 causes the program to use the first available
> partition number. Subsequent uses of the -A (--attributes), -c
> (--change-name), -t (--typecode), and -u (--partition-guid) options
> may also use 0 to refer to the same partition.

Although the documentation for the option --largest-new does not mention
such functionality, I expected it, and was puzzled when it didn't work.
