I'll be honest, for all I know logging should be global in general: it is
a pain to pass a logger to any struct that needs it. But smart people on the
internet tell me otherwise, and I do like the idea of not having any global
variables lying around.
Nonetheless, I often need to log things when locally debugging and that's a
different kind of logging than the kind you would include in the actual
released binary. For example if I want to log something from gocui, I would
rather not have gocui depend on lazygit's logging setup.
