Because for a few days I already tried to use 'C-x v B l' since
I need to check the logs of other branches many times per day,
and it was absolutely horrible experience — Shift+B is very
hard to type because "B" is in the middle of the keyboard,
and after I almost got RSI, I had to rebind it to `C-x v b l'
for the relief.
