+HEAD names the commit your changes in the working tree is based on.
+FETCH_HEAD records the branch you fetched from a remote repository
+with your last 'git-fetch' invocation.
+ORIG_HEAD is created by commands that moves your HEAD in a drastic
+way, to record the position of the HEAD before their operation, so that
+you can change the tip of the branch back to the state before you ran
+them easily.
+MERGE_HEAD records the commit(s) you are merging into your branch
+when you run 'git-merge'.

+for it. When you have two commits `r1` and `r2` (named according

+for commits that are reachable from r2 excluding those that are reachable

A similar notation "`r1\...r2`" is called symmetric difference
of `r1` and `r2` and is defined as
