REVISION RANGE SUMMARY
<rev>
           Include commits that are reachable from <rev> (i.e. <rev> and
           its ancestors).
       ^<rev>
           Exclude commits that are reachable from <rev> (i.e. <rev> and
           its ancestors).
       <rev1>..<rev2>
           Include commits that are reachable from <rev2> but exclude
           those that are reachable from <rev1>. When either <rev1> or
           <rev2> is omitted, it defaults to HEAD.
       <rev1>...<rev2>
           Include commits that are reachable from either <rev1> or
           <rev2> but exclude those that are reachable from both. When
           either <rev1> or <rev2> is omitted, it defaults to HEAD.
       <rev>^@, e.g. HEAD^@
           A suffix ^ followed by an at sign is the same as listing all
           parents of <rev> (meaning, include anything reachable from
           its parents, but not the commit itself).
       <rev>^!, e.g. HEAD^!
           A suffix ^ followed by an exclamation mark is the same as
           giving commit <rev> and then all its parents prefixed with ^
           to exclude them (and their ancestors).
       <rev>^-<n>, e.g. HEAD^-, HEAD^-2
           Equivalent to <rev>^<n>..<rev>, with <n> = 1 if not given.
       Here are a handful of examples using the Loeliger illustration
       above, with each step in the notation's expansion and selection
       carefully spelt out:
              Args   Expanded arguments    Selected commits

              B^-    = B^..B
