The code that reads from the ctags file in the completion script
(in contrib/) did not spell ${param/pattern/string} substitution
correctly, which happened to work with bash but not with zsh.

* js/completion-ctags-pattern-substitution-fix:
  contrib/completion: escape the forward slash in __git_match_ctag

Restructure "git push" codepath to make it easier to add new
configuration bits and then add push.followTags configuration that
turns --follow-tags option on by default.

* jk/push-config:
  push: allow --follow-tags to be set by config push.followTags
  cmd_push: pass "flags" pointer to config callback
  cmd_push: set "atomic" bit directly
  git_push_config: drop cargo-culted wt_status pointer

Documentation updates.

* nd/config-doc-camelCase:
  *config.txt: stick to camelCase naming convention

Test fixes.

* jk/test-annoyances:
  t5551: make EXPENSIVE test cheaper
  t5541: move run_with_cmdline_limit to test-lib.sh
  t: pass GIT_TRACE through Apache
  t: redirect stderr GIT_TRACE to descriptor 4
  t: translate SIGINT to an exit

The transfer.hiderefs support did not quite work for smart-http
transport.

* jk/smart-http-hide-refs:
  upload-pack: do not check NULL return of lookup_unknown_object
  upload-pack: fix transfer.hiderefs over smart-http

"git tag -h" used to show the "--column" and "--sort" options
that are about listing in a wrong section.

* jk/tag-h-column-is-a-listing-option:
  tag: fix some mis-organized options in "-h" listing

Output from "git log --decorate" mentions HEAD when it points at a
tip of an branch differently from a detached HEAD.

This is a potentially backward-incompatible change.

* mg/log-decorate-HEAD:
  log: decorate HEAD with branch name

"git log --decorate" did not reset colors correctly around the
branch names.

* jc/decorate-leaky-separator-color:
  log --decorate: do not leak "commit" color into the next item
  Documentation/config.txt: simplify boolean description in the syntax section
  Documentation/config.txt: describe 'color' value type in the "Values" section
  Documentation/config.txt: have a separate "Values" section
  Documentation/config.txt: describe the structure first and then meaning
  Documentation/config.txt: explain multi-valued variables once
  Documentation/config.txt: avoid unnecessary negation

Code cleanup.

* sb/leaks:
  builtin/help.c: fix memory leak
  bundle.c: fix memory leak
  connect.c: do not leak "conn" after showing diagnosis

Code cleanup.

* rs/use-isxdigit:
  use isxdigit() for checking if a character is a hexadecimal digit

Workarounds for certain build of GPG that triggered false breakage
in a test.

* mg/verify-commit:
  t7510: do not fail when gpg warns about insecure memory

"git imap-send" learned to optionally talk with an IMAP server via
libcURL; because there is no other option when Git is built with
NO_OPENSSL option, use that codepath by default under such
configuration.

* km/imap-send-libcurl-options:
  imap-send: use cURL automatically when NO_OPENSSL defined

We now detect number of CPUs on older BSD-derived systems.

* km/bsd-sysctl:
  thread-utils.c: detect CPU count on older BSD-like systems
  configure: support HAVE_BSD_SYSCTL option

Portability fixes and workarounds for shell scripts have been added
to help BSD-derived systems.

* km/bsd-shells:
  t5528: do not fail with FreeBSD shell
  help.c: use SHELL_PATH instead of hard-coded "/bin/sh"
  git-compat-util.h: move SHELL_PATH default into header
  git-instaweb: use @SHELL_PATH@ instead of /bin/sh
  git-instaweb: allow running in a working tree subdirectory

Code in "git daemon" to parse out and hold hostnames used in
request interpolation has been simplified.

* rs/daemon-hostname-in-strbuf:
  daemon: deglobalize hostname information
  daemon: use strbuf for hostname info

"git branch" on a detached HEAD always said "(detached from xyz)",
even when "git status" would report "detached at xyz".  The HEAD is
actually at xyz and haven't been moved since it was detached in
such a case, but the user cannot read what the current value of
HEAD is when "detached from" is used.

* mg/detached-head-report:
  branch: name detached HEAD analogous to status
  wt-status: refactor detached HEAD analysis

"git -C '' subcmd" refused to work in the current directory, unlike
"cd ''" which silently behaves as a no-op.

* kn/git-cd-to-empty:
  git: treat "git -C '<path>'" as a no-op when <path> is empty

The versionsort.prerelease configuration variable can be used to
specify that v1.0-pre1 comes before v1.0.

* nd/versioncmp-prereleases:
  config.txt: update versioncmp.prereleaseSuffix
  versionsort: support reorder prerelease suffixes

Also declare that the next one will be called v2.4 ;-)

Documentation fixes.

* mg/doc-status-color-slot:
  config,completion: add color.status.unmerged

"git status" now allows the "-v" to be given twice to show the
differences that are left in the working tree not to be committed.

* mg/status-v-v:
  commit/status: show the index-worktree diff with -v -v
  t7508: test git status -v
  t7508: .gitignore 'expect' and 'output' files

"git cherry-pick" used to clean-up the log message even when it is
merely replaying an existing commit.  It now replays the message
verbatim unless you are editing the message of resulting commits.

* mg/sequencer-commit-messages-always-verbatim:
  sequencer: preserve commit messages

Code simplification.

* sg/completion-remote:
  completion: simplify __git_remotes()
  completion: add a test for __git_remotes() helper function

"git rebase -i" recently started to include the number of
commits in the insn sheet to be processed, but on a platform
that prepends leading whitespaces to "wc -l" output, the numbers
are shown with extra whitespaces that aren't necessary.

* es/rebase-i-count-todo:
  rebase-interactive: re-word "item count" comment
  rebase-interactive: suppress whitespace preceding item count

Code simplification.

* ak/git-done-help-cleanup:
  git: make was_alias and done_help non-static

"git archive" can now be told to set the 'text' attribute in the
resulting zip archive.

* rs/zip-text:
  archive-zip: mark text files in archives

Code simplification.

* rs/deflate-init-cleanup:
  zlib: initialize git_zstream in git_deflate_init{,_gzip,_raw}

The current definition results in an incorrect expansion of the term under zsh.
For instance "/^${1////\\/}/" under zsh with the argument "hi" results in:
    /^/\/h/\/i/

This results in an output similar to this when trying to complete `git grep
chartab` under zsh:

    :: git grep chartabawk: cmd. line:1: /^/\/c/\/h/\/a/\/r/\/t/\/a/\/b/ { print $1 }
    awk: cmd. line:1:    ^ backslash not last character on line
    awk: cmd. line:1: /^/\/c/\/h/\/a/\/r/\/t/\/a/\/b/ { print $1 }
    awk: cmd. line:1:    ^ syntax error

Leaving the prompt in a goofy state until the user hits a key.

Escaping the literal / in the parameter expansion (using "/^${1//\//\\/}/")
results in:
    /^chartab/

allowing the completion to work correctly.

This formulation also works under bash.

* bw/kwset-use-unsigned:
  kwset: use unsigned char to store values with high-bit set

Description given by "grep -h" for its --exclude-standard option
was phrased poorly.

* nd/grep-exclude-standard-help-fix:
  grep: correct help string for --exclude-standard

"git remote add" mentioned "--tags" and "--no-tags" and was not
clear that fetch from the remote in the future will use the default
behaviour when neither is given to override it.

* mg/doc-remote-tags-or-not:
  git-remote.txt: describe behavior without --tags and --no-tags

"git diff --shortstat --dirstat=changes" showed a dirstat based on
lines that was never asked by the end user in addition to the
dirstat that the user asked for.

* mk/diff-shortstat-dirstat-fix:
