Inconsistency in wildcard selection

Problem
I think it would be better for the version "Note" information to be folded into the current dot point, which documents 0.20.1. The grammar could also be better, e.g.

From version 0.21.0 onwards, MDAnalysis supports the use of one wildcard * at the start, middle, or end of strings. u.select_atoms("resname *E") will select all atoms where the atom's residue name ends in E.

This just changed with MDAnalysis/mdanalysis#2436 – we now support fnmatch-based wildcards.

This is superseded by #55.
