Merge branch 'jc/remove-treesame-parent-in-simplify-merges' into jch

The --simplify-merges logic did not cull irrelevant parents from a
merge that is otherwise not interesting with respect to the paths
we are following.

This touches a fairly core part of the revision traversal
infrastructure; even though I think this change is correct, please
report immediately if you find any unintended side effect.

Will cook in 'next'.

* jc/remove-treesame-parent-in-simplify-merges:
  simplify-merges: drop merge from irrelevant side branch

Merge branch 'sp/smart-http-content-type-check' into jch

The smart HTTP clients forgot to verify the content-type that comes
back from the server side to make sure that the request is being
handled properly.

Will merge to 'master'.

  t5551: fix expected error output
  Verify Content-Type from smart HTTP servers
Merge branch 'nd/branch-error-cases' into jch

Fix various error messages and conditions in "git branch", e.g. we
advertised "branch -d/-D" to remove one or more branches but actually
implemented removal of zero or more branches---request to remove no
branches was not rejected.

Will merge to 'master'.

* nd/branch-error-cases:
  branch: let branch filters imply --list
  docs: clarify git-branch --list behavior
  branch: mark more strings for translation
  branch: give a more helpful message on redundant arguments
  branch: reject -D/-d without branch name

Merge branch 'jk/mergetool' into jch

Cleans up mergetool/difftool combo.

Will merge to 'master'.

* jk/mergetool:
  mergetools: simplify how we handle "vim" and "defaults"
  mergetool--lib: don't call "exit" in setup_tool
  mergetool--lib: improve show_tool_help() output
  mergetools/vim: remove redundant diff command
  git-difftool: use git-mergetool--lib for "--tool-help"

  git-mergetool: remove redundant assignment
  git-mergetool: move show_tool_help to mergetool--lib
Merge branch 'da/mergetool-docs' into jch

Build on top of the clean-up done by jk/mergetool and automatically
generate the list of mergetool and difftool backends the build
supports to be included in the documentation.

Will merge to 'master'.

* da/mergetool-docs:
  doc: generate a list of valid merge tools
  mergetool--lib: list user configured tools in '--tool-help'

Merge branch 'ss/mergetools-tortoise' into jch

Update mergetools to work better with newer merge helper tortoise ships.

Will merge to 'master'.

* ss/mergetools-tortoise:

Merge branch 'jk/python-styles' into jch

Will merge to 'master'.

* jk/python-styles:
  CodingGuidelines: add Python coding guidelines
Merge branch 'jk/remote-helpers-doc' into jch

"git help remote-helpers" did not work; 'remote-helpers' is not
a subcommand name but a concept, so its documentation should have
been in gitremote-helpers, not git-remote-helpers.

Will merge to 'master'.

* jk/remote-helpers-doc:
  Rename {git- => git}remote-helpers.txt

Conflicts:
	Documentation/Makefile
Merge branch 'ct/autoconf-htmldir' into jch

The autoconf subsystem passed --mandir down to generated
config.mak.autogen but forgot to do the same for --htmldir.

Will merge to 'master'.

* ct/autoconf-htmldir:
  Honor configure's htmldir switch

Conflicts:
	config.mak.in
Merge branch 'jc/combine-diff-many-parents' into jch

We used to have an arbitrary 32 limit for combined diff input,
resulting in incorrect number of leading colons shown when showing
the "--raw --cc" output.

Will merge to 'master'.

* jc/combine-diff-many-parents:
  t4038: add tests for "diff --cc --raw <trees>"
  combine-diff: lift 32-way limit of combined diff
Merge branch 'jk/apply-similaritly-parsing' into jch

Make sure the similarity value shown in the "apply --summary"
output is sensible, even when the input had a bogus value.

Will merge to 'master'.

* jk/apply-similaritly-parsing:
  builtin/apply: tighten (dis)similarity index parsing

Merge branch 'mp/complete-paths' into jch

The completion script used to let the default completer to suggest
pathnames, which gave too many irrelevant choices (e.g. "git add"
would not want to add an unmodified path).  Teach it to use a more
git-aware logic to enumerate only relevant ones.

This is logically the right thing to do, and we would really love
to see people who have been involved in completion code to review
and comment on the implementation.

Will cook in 'next' to see if anybody screams.

* mp/complete-paths:
  git-completion.bash: add support for path completion
Merge branch 'mk/tcsh-complete-only-known-paths' into jch

Manlio's "complete with known paths only" update to completion
scripts returns directory names without trailing slash to
compensate the addition of '/' done by bash that reads from our
completion result.  tcsh completion code that reads from our
internal completion result does not add '/', so let it ask our
complletion code to keep the '/' at the end.

Will merge to 'master'.

* mk/tcsh-complete-only-known-paths:
  completion: handle path completion and colon for tcsh script
Merge branch 'jc/push-2.0-default-to-simple' into jch

Will cook in 'next' until Git 2.0 ;-).

  t5551: do not assume the "matching" push is the default
  t5550: do not assume the "matching" push is the default
  doc: push.default is no longer "matching"
