[PATCH v3 0/8] Name for A..B ranges?

This is the re-roll of the po/range-doc (2016-07-01) 3 commits and its
follow on patch.

The series has gained additional patches following the discussions
($gmane/298790).

The original first 3 patches are unchanged, though 2/8 has been inserted
to name the Left and Right ranges.

The extra four patches carefully tease out the clarification of
reachability. Reachability is defined relative the ancestry chain thus
(hopefully) avoiding misunderstandings.

The final patch updates the summary examples, and the tricky (for the
untutored reader) two dots case of a linear development where r1..r2
excludes r1 itself.

The patches can be squashed together if required.

V1 patch series $gmane/298223
V2 patch series $gmane/298689
