The graph test in t9400 covers the case of two simultaneous
branches, but all of the commits during this time are on the
right-hand branch. So we test a graph structure like:
| |
| * commit ...
| |
but we never see the reverse, a commit on the left-hand
branch:
| |
* | commit ...
| |
Since this is an easy thing to get wrong when touching the
graph-matching code, let's cover it by adding one more
commit with its timestamp interleaved with the other branch.
Note that we need to pass --date-order to convince Git to
show it this way (since --topo-order tries to keep lines of
history separate).
