blackbox: also log alias expansions
This should be extremely useful for helping users debug without having
to see their complete configuration.
Shell aliases do not get their expansion logged, because we don't look
and see if we're in a repo before we dive into the execution of a
shell alias. As a result, the ui object doesn't know where to log.
