+<revision range>::
+ Show only commits in the specified revision range. When no
+ <revision range> is specified, it defaults to `HEAD` (i.e. the
+ whole history leading to the current commit). `origin..HEAD`
+ specifies all the commits reachable from the current commit
+ (i.e. `HEAD`), but not from `origin`. For a complete list of
+ ways to spell <revision range>, see the "Specifying Ranges"
+ section of linkgit:gitrevisions[7].
+
+[\--] <path>...::
+ Consider only commits that are enough to explain how the files
+ that match the specified paths came to be.
++
+Paths may need to be prefixed with "\-- " to separate them from
+options or the revision range, when confusion arises.
