verbose is quite a popular flag name, such that the option parsing
dedicated it its own macro OPT__VERBOSE.

While this is defensive programming (checking the pointer before dereferencing
it, the first condition (commit == NULL) should never be false here,
as the caller
checks for argc == 2 ? Maybe we could move the logic of the whole
condition there
if (command == SETUP_REFLOG && argc == 2 && *argv[1])
return !!setup_reflog_action(&opts, argv[1], verbose);
as then we could loose the outer conditional here.
