[LACKS SIGNOFF] remote-hg: bugfix for fetching non local remotes

6796d49 introduced a bug by making shared_path == ".git/hg' which
will most likely exist already, causing a new remote never to be
cloned and subsequently causing hg.share to fail with error msg:
"mercurial.error.RepoError: repository .git/hg not found"

Changing gitdir to dirname causes shared_path ==
.git/hg/<remote_name>/hg. The call to hg.share with local_path ==
.git/hg/<remote_name>/clone works again.

This requires the platform lstat() to be correct to avoid false
negatives.

* mh/ref-races-optim-invalidate-cached:
  refs: do not invalidate the packed-refs cache unnecessarily

* jm/doc-ref-prune:
  Documentation: fix git-prune example usage

Merge branch 'ml/avoid-using-grep-on-crlf-files' into jch

On systems that understand a CRLF as a line ending, tests in this
script that worked on files with CRLF line endings using "grep" to
extract matching lines may lose the CR at the end of lines that
match, causing the actual output not to match the expected output.

* ml/avoid-using-grep-on-crlf-files:
  test-lib.sh - define and use GREP_STRIPS_CR
Merge branch 'jk/cat-file-batch-optim' into jch

If somebody wants to only know on-disk footprint of an object
without having to know its type or payload size, we can bypass a
lot of code to cheaply learn it.

* jk/cat-file-batch-optim:
  Fix some sparse warnings
  sha1_object_info_extended: pass object_info to helpers
  sha1_object_info_extended: make type calculation optional
  packed_object_info: make type lookup optional
  packed_object_info: hoist delta type resolution to helper
  sha1_loose_object_info: make type lookup optional
  sha1_object_info_extended: rename "status" to "type"
  cat-file: disable object/refname ambiguity check for batch mode

Merge branch 'sb/traverse-trees-bitmask-variable-name' into jch

  traverse_trees(): clarify return value of the callback
Merge branch 'rj/sparse' into jch

* rj/sparse:
  Revert "compat/unsetenv.c: Fix a sparse warning"
Merge branch 'ml/cygwin-updates' into jch

The tip one does _not_ revert c869753e (Force core.filemode to
false on Cygwin., 2006-12-30) on purpose, so that people can
still retain the old behaviour if they wanted to.

* ml/cygwin-updates:
  cygwin: stop forcing core.filemode=false
  Cygwin 1.7 supports mmap
  Cygwin 1.7 has thread-safe pread
  Cygwin 1.7 needs compat/regex
Merge branch 'es/contacts' into jch

A helper to read from a set of format-patch output files or a range
of commits and find those who may have insights to the code that
the changes touch by running a series of "git blame" commands.

* es/contacts:
  contrib: contacts: add documentation
  contrib: contacts: add mailmap support
  contrib: contacts: interpret committish akin to format-patch
  contrib: contacts: add ability to parse from committish
  contrib: add git-contacts helper
Merge branch 'ob/typofixes' into jch

* ob/typofixes:
  typofix: in-code comments
  typofix: documentation
  typofix: release notes
Merge branch 'mh/multimail' into jch

An enhanced "post-receive" hook to send e-mail messages.

* mh/multimail:
  post-receive-email: deprecate script in favor of git-multimail
  git-multimail: an improved replacement for post-receive-email
Merge branch 'km/svn-1.8-serf-only' into jch

Subversion 1.8.0 that was recently released breaks older subversion
clients coming over http/https in various ways.

* km/svn-1.8-serf-only:
  Git.pm: revert _temp_cache use of temp_is_locked
  git-svn: allow git-svn fetching to work using serf
  Git.pm: add new temp_is_locked function
Merge branch 'jc/check-x-z' into jch

"git check-ignore -z" applied the NUL termination to both its input
(with --stdin) and its output, but "git check-attr -z" ignored the
option on the output side.

This is potentially a backward incompatible fix.  I am tempted to
merge this to and keep it in 'next' for a while to see if anybody
screams before deciding if we want to do anything to help existing
users (there may be none).

* jc/check-x-z:
  check-attr -z: a single -z should apply to both input and output
  check-ignore -z: a single -z should apply to both input and output
  check-attr: the name of the character is NUL, not NULL
  check-ignore: the name of the character is NUL, not NULL

# Conflicts:
# 	builtin/check-ignore.c
Merge branch 'ms/fetch-prune-configuration' into jch

Allow fetch.prune and remote.*.prune configuration variables to be set,
and "git fetch" to behave as if "--prune" is given.

"git fetch" that honors remote.*.prune is fine, but I wonder if we
should somehow make "git push" aware of it as well.  Perhaps
remote.*.prune should not be just a boolean, but a 4-way "none",
"push", "fetch", "both"?

* ms/fetch-prune-configuration:
  fetch: make --prune configurable
Merge branch 'rj/doc-rev-parse' into jch

* rj/doc-rev-parse:
  rev-parse(1): logically group options
  rev-parse: remove restrictions on some options
Merge branch 'jc/pull-training-wheel' into jch

Make "git pull" (without arguments that say what branch to
integrate from where) refuse with "it does not fast forward; choose
between 'pull --merge' and 'pull --rebase'".

http://thread.gmane.org/gmane.comp.version-control.git/225146/focus=229221

for full discussion.

* jc/pull-training-wheel:
  pull: require choice between rebase/merge on non-fast-forward pull
Merge branch 'jc/diff-filter-negation' into jch

Teach "git diff --diff-filter" to express "I do not want to see
these classes of changes" more directly by listing only the
unwanted ones in lowercase (e.g. "--diff-filter=d" will show
everything but deletion) and deprecate "diff-files -q" which did
the same thing as "--diff-filter=d".

* jc/diff-filter-negation:
  diff: deprecate -q option to diff-files
  diff: allow lowercase letter to specify what change class to exclude
  diff: reject unknown change class given to --diff-filter
  diff: preparse --diff-filter string argument
  diff: factor out match_filter()
  diff: pass the whole diff_options to diffcore_apply_filter()
