Git ships with a fall-back regexp implementation for platforms with
buggy regexp library; give people a tool to see if they should be
using it on their platform.

  merge_bases_many(): split out the logic to paint history
  in_merge_bases(): omit unnecessary redundant common ancestor reduction
  http-push: use in_merge_bases() for fast-forward check
  receive-pack: use in_merge_bases() for fast-forward check
  in_merge_bases(): support only one "other" commit

* nd/i18n-index-pack:
  i18n: mark more index-pack strings for translation

"git show --format='%ci'" did not give timestamp correctly for
commits created without human readable name on "committer" line.

"git branch --set-upstream origin/master" is a common mistake to
create a local branch 'origin/master' and set it to integrate with
the current branch.  With a plan to deprecate this option, introduce
"git branch (-u|--set-upstream-to) origin/master" that sets the
current branch to integrate with 'origin/master' remote tracking
branch.

* cn/branch-set-upstream-to:
  branch: deprecate --set-upstream and show help if we detect possible mistaken use
  branch: add --unset-upstream option
  branch: introduce --set-upstream-to

"git cherry-pick A C B" used to replay changes in A and then B and
then C if these three commits had committer timestamps in that
order, which is not what the user who said "A C B" naturally expects.

* mz/cherry-pick-cmdline-order:
  cherry-pick/revert: respect order of revisions to pick
  demonstrate broken 'git cherry-pick three one two'
  teach log --no-walk=unsorted, which avoids sorting

We tried to bend backwards to allow "--quiet" to be a synonym as
"-s" when given as e.g. "git show --quiet", but did not quite
succeed.

* jk/maint-quiet-is-synonym-to-s-in-log:
  log: fix --quiet synonym for -s

* ph/credential-gnome-keyring:
  contrib: add credential helper for GnomeKeyring
