A merge is not necessarily with a remote branch, it can be with any
commit object.

---------------
A merge is always between the current `HEAD` and one or more
-remote branch heads, and the index file must exactly match the
+commit objects (usually, branch head or tag), and the index file must
+exactly match the
tree of `HEAD` commit (i.e. the contents of the last commit) when
it happens. In other words, `git-diff --cached HEAD` must
report no changes.
