This implies the '--topo-order' option by default, but the
'--date-order' option may also be specified.

reflog entries from the most recent one to older ones.
When this option is used you cannot specify commits to
exclude (that is, '{caret}commit', 'commit1..commit2',
- nor 'commit1...commit2' notations cannot be used).
+ nor 'commit1\...commit2' notations cannot be used).

With '\--pretty' format other than oneline (for obvious reasons),
this causes the output to have two extra lines of information
merges from the resulting history, as there are no selected
commits contributing to this merge.
+--ancestry-path::
+
+ When given a range of commits to display (e.g. 'commit1..commit2'
+ or 'commit2 {caret}commit1'), only display commits that exist
+ directly on the ancestry chain between the 'commit1' and
+ 'commit2', i.e. commits that are both descendants of 'commit1',
+ and ancestors of 'commit2'.
+
A more detailed explanation follows.
Suppose you specified `foo` as the <paths>. We shall call commits
+
-----------------------------------------------------------------------

one of the parents is TREESAME, we follow only that one, so the other
sides of the merge are never walked.
-Finally, there is a fourth simplification mode available:
-
--simplify-merges::
First, build a history graph in the same way that
removed completely, because it had one parent and is TREESAME.
--
+Finally, there is a fifth simplification mode available:
+
+--ancestry-path::
+
+ Limit the displayed commits to those directly on the ancestry
+ chain between the "from" and "to" commits in the given commit
+ range. I.e. only display commits that are ancestor of the "to"
+ commit, and descendants of the "from" commit.
++
+As an example use case, consider the following commit history:
++
+-----------------------------------------------------------------------
+ D---E-------F
+ / \ \
+ B---C---G---H---I---J
+ / \
+ A-------K---------------L--M
+-----------------------------------------------------------------------
++
+A regular 'D..M' computes the set of commits that are ancestors of `M`,
+but excludes the ones that are ancestors of `D`. This is useful to see
+what happened to the history leading to `M` since `D`, in the sense
+that "what does `M` have that did not exist in `D`". The result in this
+example would be all the commits, except `A` and `B` (and `D` itself,
+of course).
++
+When we want to find out what commits in `M` are contaminated with the
+bug introduced by `D` and need fixing, however, we might want to view
+only the subset of 'D..M' that are actually descendants of `D`, i.e.
+excluding `C` and `K`. This is exactly what the '\--ancestry-path'
+option does. Applied to the 'D..M' range, it results in:
++
+-----------------------------------------------------------------------
+ E-------F
+ \ \
+ G---H---I---J
+ \
+ L--M
+-----------------------------------------------------------------------
+
The '\--simplify-by-decoration' option allows you to view only the
big picture of the topology of the history, by omitting commits
that are not referenced by tags. Commits are marked as !TREESAME
