This will be the same as for the tree sorting. You can regard the
replies as a partial ordering between the mails. In this case
The relation first > third is already present since
first > second > third. Thus you get something like
first
├─> second
| └─> third
└─> fourth
However, if you now add a fifth message replying to third and fourth you
get
first
├─> second
| └─> third
└───│> fourth
└┴─> fifth
A more messy example is given below
1 r F 2004-09-17 To AH 0.2K dag test 1
2 r F 2004-09-17 To AH 0.2K ├─>Re: dag test 1 -> 2
