Well actually it's not just everything containing a special character,
it's also anything with leading or trailing whitespace, and empty
strings (not sure that can ever happen in practice).

It's because of the potential for bugs in this area, that I'd propose
just quoting everything (except numeric values) as in my original
patch.
