[PATCH v2 0/8] New git-cc-cmd helper

Hi,

This script allows you to get a list of relevant persons to Cc when sending a patch series.

  % git cc-cmd v1.8.1.6^^1..v1.8.1.6^^2
  "Henrik Grubbström" <grubba@grubba.org> (author: 7%)
  junio (signer: 84%, author: 15%)
  "Nguyễn Thái Ngọc Duy" <pclouds@gmail.com> (author: 30%, signer: 7%)
  "Jean-Noël AVILA" <avila.jn@gmail.com> (author: 7%)
  Jean-Noel Avila <jn.avila@free.fr> (signer: 7%)
  Duy Nguyen <pclouds@gmail.com> (author: 7%)
  Michael Haggerty <mhagger@alum.mit.edu> (author: 15%)
  Clemens Buchacher <drizzd@aon.at> (author: 7%)
  Joshua Jensen <jjensen@workspacewhiz.com> (author: 7%)
  Johannes Sixt <j6t@kdbg.org> (signer: 7%)

The code finds the changes in each commit in the list, runs 'git blame' to see which other commits are relevant to those lines, and then adds the author and signer to the list.

Finally, it calculates what percentage of the total relevant commits each person was involved in, and if it passes the threshold, it goes in.

You can also choose to show the commits themselves:

  % git cc-cmd --commits v1.8.1.6^^1..v1.8.1.6^^2
  9db9eec attr: avoid calling find_basename() twice per path
  94bc671 Add directory pattern matching to attributes
  82dce99 attr: more matching optimizations from .gitignore
  593cb88 exclude: split basename matching code into a separate function
  b559263 exclude: split pathname matching code into a separate function
  4742d13 attr: avoid searching for basename on every match
  f950eb9 rename pathspec_prefix() to common_prefix() and move to dir.[ch]
  4a085b1 consolidate pathspec_prefix and common_prefix
  d932f4e Rename git_checkattr() to git_check_attr()
  2d72174 Extract a function collect_all_attrs()
  8cf2a84 Add string comparison functions that respect the ignore_case variable.
  407a963 Merge branch 'rr/remote-helper-doc'
  ec775c4 attr: Expand macros immediately when encountered.

But wait, there's more: you can also specify a list of patch files, which means this can be used for git send-emails --cc-cmd option.
