I had confused myself.

My test case `git log --graph --format="%<(19,mtrunc)%d=2" -6` had a
2-char step in the graph that I confused with the effects between
repeated runs with the 'N' value adjusted by +1 and -1.

I then jumped to conclusions about the integer division in the mid
string position of the mtrunc case win the code.

Sorry for that.
