If we want to continue that tried-and-proven approach as a
short-term fix, a patch may look like this.
We use "unspecified" value to initialize the main variables
(status_format global and s->show_branch), and also prepare
"from-config" counterpart variables. After we read both, we figure
out which one should be used, while resetting the main variables to
their default if neither mechanism touched them.
