Well, by "at least", what I meant was that it might make sense
to pass "--full-history" option to be more compatible with the
original output.  For graphical output like gitk, --full-history
makes a mess on the screen, but a list-oriented output like
gitweb it might be less confusing to show all the alternate
paths that touched the path than leaving some histories out.
