So what's the point of it? 'my @val = git_get_project_config ()' just
creates an array with one element.

Hm, actually not at all. Now, if I have a setup like Junio wrote the
git_get_project_config just returns an array ref. So modifying the
feature_extra_branch_refs to handle the returned value as either simple
scalar or array reference should be enough.

Oi, that was an omission from my side - at first I had that git config
setting with underscores. I removed them when I noticed that underscores
are not used there. Apparently I missed that one.
