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.
