[PATCH v2 0/8] completion: add option completion for most builtin commands

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

This series adds option completion for many more commands. More
importantly it introduces a generic completion function
__git_complete_common(). With --git-completion-helper providing more
and more information in future, this function can start to replace
many other _git_xxx() in this file.

Nguyễn Thái Ngọc Duy (8):
  git.c: move cmd_struct declaration up
  git.c: add hidden option --list-parseopt-builtins
  completion: mention the oldest version we need to support
  completion: factor out _git_xxx calling code
  completion: add --option completion for most builtin commands
  completion: delete option-only completion commands
  completion: use __gitcomp_builtin in _git_ls_tree
  completion: use __gitcomp_builtin in _git_cherry
