If the nounset option is set, the following error occurs when _generic
is used:
_generic:3: curcontext: parameter not set
This is because _generic runs before options are setup in
_main_complete. A wrapper script might setup some initial context so
the patch I'm suggesting below is to use ${curcontext:-} instead of
making it ignore any existing $curcontext.
I can't help wondering if it would have been better is nounset was set
globally for completion functions though because it might help avoid
bugs.
