Actually, the code needs to be able to differentiate between

	git status --no-short
        git status

the former telling us explicitly to defeat status.short while the
latter telling us to use whatever random value we happen to have in
the configuration.  Initializing the variable to UNSPECIFIED is one
way to achieve that, as the former will explicitly set it to NONE
while the latter will leave it UNSPECIFIED when the command line
parsing finishes.
