Is a new option necessary, or can we just use gnulib's quotearg() module unconditionally? I guess the only reason to make it a new command-line option would be to allow the user to specify which of the quotearg styles they prefer to see (for reference, 'ls --quoting-style=WORD' is a good example of producing various representations of the output to avoid ambiguities). If we do use gnulib's quotearg module, we also benefit from QUOTING_STYLE in the environment regardless of whether we add a command-line option. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3226 Virtualization: qemu.org | libvirt.org
