I am late to the party, but I cannot get how the latter is viable.
If "A" had parent "B" whose parent was "C" that is root, wouldn't we
see the same output?  Or are we adding " parentless" at the end of
the one-liner log message?

The former, with the understanding that "two '*' commit marks
vertically adjacent have parent-child relationship, otherwise we
draw line between '*' to connect them if they have parent-child
relationship", does not have such a problem.
