I would hope that the definition is that these config variables are
simply "name=value" pairs with simple quoting.  I wouldn't even go so
far as to allow the the quoting to be "sh-like" (I can't imagine any
reason to use some of the more complex forms of shell quoting!).

Unfortunately this does mean that a real-world implementation MUST avoid
using /bin/sh to parse these variable settings.  Assuming that the
syntax definition is restricted for the express purpose of making it
possible to parse these variable settings in other ways that totally
avoid using /bin/sh, any use of /bin/sh directly would present just too
many opportunities for users to do undefined things.
