[PATCH v2 0/2] doc: apply new format to git-branch man page

Working on git-branch's doc uncovered a bug in the completion logic that did not take into account the new formatting of options. Apart from that, the changes are quite standard now.

Changes since V1:

 * rework commit messages
 * De-GNU-ify and simplify script

Jean-Noël Avila (2):
  completion: take into account the formatting backticks for options
  doc: apply new format to git-branch man page
