Git status bar fails to track current branch

[jtsom]

Issue Type: Bug

Switching branches in a terminal panel, or external terminal, fails to update the current branch indicator in the lower left of the window. Switching branches by clicking on the current branch, and choosing a branch in the menu that appears, does update the status bar.
