Why "local" only on one side and not the other?

Also switching on "$b" and relying on how it happens to be formatted
inside parentheses when detached (which can very well change in the
future) looks like a fragile bug waiting to be triggered.

You gave nice symbolic names to branch_color and flags_color, but
these two use hardcoded colors?
