Portability fix.

* js/sleep-without-select:
  lockfile: wait using sleep_millisec() instead of select()

  lockfile: replace random() by rand()

A compilation workaround.

* es/utf8-stupid-compiler-workaround:
  utf8: NO_ICONV: silence uninitialized variable warning

"git am" learned am.threeWay configuration variable.

* rl/am-3way-config:
  git-am: add am.threeWay config variable
  t4150-am: refactor am -3 tests
  git-am.sh: fix initialization of the threeway variable

Traditionally, external low-level 3-way merge drivers are expected
to produce their results based solely on the contents of the three
variants given in temporary files named by %O, %A and %B on their
command line.  Additionally allow them to look at the final path
(given by %P).

* jc/ll-merge-expose-path:
  ll-merge: pass the original path to external drivers

* es/osx-header-pollutes-mask-macro:
  ewah: use less generic macro name
  ewah/bitmap: silence warning about MASK macro redefinition

Auto-detect availability of getdelim() that helps optimized version
of strbuf_getwholeline().

* es/configure-getdelim:
  configure: add getdelim() check
  config.mak.uname: Darwin: define HAVE_GETDELIM for modern OS X releases

"git pull" has become more aware of the options meant for
underlying "git fetch" and then learned to use parse-options
parser.

* pt/pull-optparse:
  pull: use git-rev-parse --parseopt for option parsing
  pull: handle git-fetch's options as well

"git blame" learned blame.showEmail configuration variable.

* qn/blame-show-email:
  blame: add blame.showEmail configuration

"git format-patch --ignore-if-upstream A..B" did not like to be fed
tags as boundary commits.

* jc/do-not-feed-tags-to-clear-commit-marks:
  format-patch: do not feed tags to clear_commit_marks()

"git send-email" learned to handle more forms of sendmail style
aliases file.

* es/send-email-sendmail-alias:
  send-email: further warn about unsupported sendmail aliases features
  t9001: add sendmail aliases line continuation tests
  t9001: refactor sendmail aliases test infrastructure
  send-email: implement sendmail aliases line continuation support
  send-email: simplify sendmail aliases comment and blank line recognizer
  send-email: refactor sendmail aliases parser
  send-email: fix style: cuddle 'elsif' and 'else' with closing brace
  send-email: drop noise comments which merely repeat what code says
  send-email: visually distinguish sendmail aliases parser warnings
  send-email: further document missing sendmail aliases functionality

"git apply" cannot diagnose a patch corruption when the breakage is
to mark the length of the hunk shorter than it really is on the
hunk header line "@@ -l,k +m,n @@"; one special case it could is
when the hunk becomes no-op (e.g. k == n == 2 for two-line context
patch output), and it learned how to do so.

* jc/apply-reject-noop-hunk:
  apply: reject a hunk that does not do anything

Code clean-up.

* jk/clone-dissociate:
  clone: reorder --dissociate and --reference options
  clone: use OPT_STRING_LIST for --reference

* sb/submodule-doc-intro:
  submodule doc: reorder introductory paragraphs

* sb/glossary-submodule:
  glossary: add "remote", "submodule", "superproject"

A few usage string updates.

* ah/usage-strings:
  blame, log: format usage strings similarly to those in documentation

Doc grammar fix.

* mc/commit-doc-grammofix:
  Documentation/git-commit: grammofix

Code clean-up.

* rs/janitorial:
  dir: remove unused variable sb
  clean: remove unused variable buf
  use file_exists() to check if a file exists in the worktree

An earlier leakfix to bitmap testing code was incomplete.

* sb/test-bitmap-free-at-end:
  test_bitmap_walk: free bitmap with bitmap_free

"git clean pathspec..." tried to lstat(2) and complain even for
paths outside the given pathspec.

* dt/clean-pathspec-filter-then-lstat:
  clean: only lstat files in pathspec

Communication between the HTTP server and http_backend process can
lead to a dead-lock when relaying a large ref negotiation request.
Diagnose the situation better, and mitigate it by reading such a
request first into core (to a reasonable limit).

* jk/http-backend-deadlock:
  http-backend: spool ref negotiation requests to buffer
  t5551: factor out tag creation
  http-backend: fix die recursion with custom handler

The clean/smudge interface did not work well when filtering an
empty contents (failed and then passed the empty input through).
It can be argued that a filter that produces anything but empty for
an empty input is nonsense, but if the user wants to do strange
things, then why not?

* jh/filter-empty-contents:
  sha1_file: pass empty buffer to index empty file

Make "git stash something --help" error out, so that users can
safely say "git stash drop --help".

* jk/stash-options:
  stash: recognize "--help" for subcommands
  stash: complain about unknown flags

Clarify that "log --raw" and "log --format=raw" are unrelated
concepts.

* mm/log-format-raw-doc:
  Documentation/log: clarify sha1 non-abbreviation in log --raw
  Documentation/log: clarify what --raw means

Catch a programmer mistake to feed a pointer not an array to
ARRAY_SIZE() macro, by using a couple of GCC extensions.

* ep/do-not-feed-a-pointer-to-array-size:
  git-compat-util.h: implement a different ARRAY_SIZE macro for for safely deriving the size of array

An earlier optimization broke index-pack for a large object
transfer; this fixes it before the breakage hits any released
version.

* nd/slim-index-pack-memory-usage:
  index-pack: fix truncation of off_t in comparison

Doc updates.

* sb/pack-protocol-mention-smart-http:
  Documentation/technical/pack-protocol: mention http as possible protocol

Build clean-up.

* jk/make-fix-dependencies:
  Makefile: silence perl/PM.stamp recipe
  Makefile: avoid timestamp updates to GIT-BUILD-OPTIONS
  Makefile: drop dependency between git-instaweb and gitweb

The setup code used to die when core.bare and core.worktree are set
inconsistently, even for commands that do not need working tree.

* jk/die-on-bogus-worktree-late:
  setup_git_directory: delay core.bare/core.worktree errors

Doc updates.

* sg/merge-summary-config:
  Documentation: include 'merge.branchdesc' for merge and config as well

"git send-email" learned the alias file format used by the sendmail
program (in an abbreviated form).

* ah/send-email-sendmail-alias:
  t9001: write $HOME/, not ~/, to help shells without tilde expansion
  send-email: add sendmail email aliases format

l10n-2.4-maint-de-updates

* tag 'l10n-2.4-maint-de-updates' of git://github.com/git-l10n/git-po:
  l10n: de.po: translation fix for fall-back to 3way merge
  l10n: de.po: punctuation fixes
  l10n: de.po: grammar fix
  l10n: de.po: change error message from "sagen" to "Meinten Sie"

The English version is correct, but misleading: It is not the 3way merge
that is being patched also, but that is being fallen back to also.

The German version translates the former meaning. Make it translate the
latter.

We should not use "sagen" if someone has written something wrong.
Although it's "say" in English, we should not use it in German
and instead use our normal error message.
