[Greg Hudson via RT]

Always set appdefault_get() output argument

gcc 7 cannot determine that appdefault_get() always sets *ret_value
when it returns zero, so issues a "may be used uninitialized" warning
in its caller.  Set *ret_value at the beginning of the function body
in accordance with current practices.
