From d9c6469f38737e9c96428a81adf0fc4d97606bb0 Mon Sep 17 00:00:00 2001 From: Jonathan Gilbert Date: Sun, 1 Dec 2019 02:28:32 +0000 Subject: git-gui: update status bar to track operations Update the status bar to track updates as individual "operations" that can overlap. Update all call sites to interact with the new status bar mechanism. Update initialization to explicitly clear status text, since otherwise it may persist across future operations.
