* A new "push.followTags" configuration turns the "--follow-tags"
option on by default for the "git push" command.
+ * "git log --graph --no-walk A B..." is a conflicting request that
+ asks nonsense; no-walk tells us show discrete points in the
+ history, while graph asks to draw connections between these
+ discrete points. Forbid the combination.
+
+ * "git rev-list --bisect --first-parent" does not work (yet) and can
+ even cause SEGV; forbid it. "git log --bisect --first-parent"
+ would not be useful until "git bisect --first-parent" materializes,
+ so it is also forbidden for now.

Performance, Internal Implementation, Development Support etc.
* "git push" codepath has been restructured to make it easier to add
new configuration bits.
+ * The run-command interface was easy to abuse and make a pipe for us
+ to read from the process, wait for the process to finish and then
+ attempt to read its output, which is a pattern that lead to a
+ deadlock. Fix such uses by introducing a helper to do this
+ correctly (i.e. we need to read first and then wait the process to
+ finish) and also add code to prevent such abuse in the run-command
+ helper.

Also contains various documentation updates and code clean-ups.
that are about listing in a wrong section.
(merge dd059c6 jk/tag-h-column-is-a-listing-option later to maint).
+ * "git prune" used to largely ignore broken refs when deciding which
+ objects are still being used, which could spread an existing small
+ damage and make it a larger one.
+ (merge ea56c4e jk/prune-with-corrupt-refs later to maint).
+
+ * The split-index mode introduced at v2.3.0-rc0~41 was broken in the
+ codepath to protect us against a broken reimplementation of Git
+ that writes an invalid index with duplicated index entries, etc.
+ (merge 03f15a7 tg/fix-check-order-with-split-index later to maint).
+
+ * "git fetch" that fetches a commit using the allow-tip-sha1-in-want
+ extension could have failed to fetch all the requested refs.
+ (merge 32d0462 jk/fetch-pack later to maint).
+
+ * An failure early in the "git clone" that started creating the
+ working tree and repository could have resulted in some directories
+ and files left without getting cleaned up.
+ (merge 16eff6c jk/cleanup-failed-clone later to maint).

+ * Recommend format-patch and send-email for those who want to submit
+ patches to this project.

+ * Even though "git grep --quiet" is run merely to ask for the exit
+ status, we spawned the pager regardless. Stop doing that.
+ (merge c2048f0 ws/grep-quiet-no-pager later to maint).

+ * The prompt script (in contrib/) did not show the untracked sign
+ when working in a subdirectory without any untracked files.
