cargo package: please provide a --list0 option to print NUL-terminated filenames

[joshtriplett]

cargo package --list lists all the filenames the .crate file would include, followed by newlines. A crate could potentially include a file whose name includes a newline, such as for test data. Please consider providing a cargo package --list0 option to list filenames followed by NUL characters instead of newlines.

(After adding such an option, cargo package --list should probably fail with an error and no other output if any filename includes a newline, to catch errors.)

Sounds plausible to me!

Or we could disallow these characters. I haven't seen legitimate use cases for file names with newlines in them, @joshtriplett do you know any?

Test cases; no other legitimate use that I can think of.
