Merge branch 'mg/more-textconv' into pu

Make "git grep" and "git show" pay attention to --textconv when
dealing with blob objects.

I thought this was pretty well designed and executed, but it seems
there are some doubts on the list; kicking back to 'pu'.

* mg/more-textconv:
  grep: honor --textconv for the case rev:path
  grep: allow to use textconv filters
  t7008: demonstrate behavior of grep with textconv
  cat-file: do not die on --textconv without textconv filters
  show: honor --textconv for blobs
  diff_opt: track whether flags have been set explicitly
  t4030: demonstrate behavior of show with textconv

# Conflicts:
# 	object.c
# 	object.h
# 	t/t8007-cat-file-textconv.sh
Merge branch 'jl/submodule-mv' into pu

"git mv A B" when moving a submodule A does "the right thing",
inclusing relocating its working tree and adjusting the paths in
the .gitmodules file.

* jl/submodule-mv:
  submodule.c: duplicate real_path's return value
  rm: delete .gitmodules entry of submodules removed from the work tree
  Teach mv to update the path entry in .gitmodules for moved submodules
  Teach mv to move submodules using a gitfile
  Teach mv to move submodules together with their work trees
Merge branch 'jk/submodule-subdirectory-ok' into pu

Allow various subcommands of "git submodule" to be run not from the
top of the working tree of the superproject.

* jk/submodule-subdirectory-ok:
  submodule: fix quoting in relative_path()
  submodule: drop the top-level requirement
  rev-parse: add --prefix option
Merge branch 'fc/remote-helpers-use-specified-python' into pu

I do not particularly think the second from the bottom is a good
change, but it takes the remainder of the series hostage.

* fc/remote-helpers-use-specified-python:
  remote-helpers: add exec-path links
  remote-helpers: allow direct test execution
  remote-helpers: rename tests
  remote-helpers: generate scripts
Merge branch 'fc/sequencer-skip-quiet' into pu

The bottom three looked more or less reasonable.  Execution of
post-rewrite hook could use a better refactoring from the original
code copied from builtin/commit.c, though.

* fc/sequencer-skip-quiet:
  sequencer: run post-rewrite hook
  cherry-pick: store rewritten commits
  cherry-pick: add --skip-empty option
  sequencer: avoid leaking message buffer when refusing to create an empty commit
  sequencer: remove useless indentation
Merge branch 'ap/diff-ignore-blank-lines' into pu

"git diff" learned a mode that ignores hunks whose change consists
only of additions and removals of blank lines, which is the same as
"diff -B" (ignore blank lines) of GNU diff.

* ap/diff-ignore-blank-lines:
  diff: add --ignore-blank-lines option
Merge branch 'tr/test-v-and-v-subtest-only' into pu

Allows N instances of tests run in parallel, each running 1/N parts
of the test suite under Valgrind, to speed things up.

The tip one may be useful in practice but is a tad ugly ;-)

There seem to be some miscounting by toggling the verbose/valgrind
mode at wrong places?  Cf. $gmane/225735

* tr/test-v-and-v-subtest-only:
  test-lib: support running tests under valgrind in parallel
  test-lib: allow prefixing a custom string before "ok N" etc.
  test-lib: valgrind for only tests matching a pattern
  test-lib: verbose mode for only tests matching a pattern
  test-lib: refactor $GIT_SKIP_TESTS matching
  test-lib: enable MALLOC_* for the actual tests
Merge branch 'jh/shorten-refname' into pu

When remotes/origin/HEAD is not a symbolic ref, "rev-parse
--abbrev-ref remotes/origin/HEAD" ought to show "origin", not
"origin/HEAD", which is fixed with this series (if it is a symbolic
ref that points at remotes/origin/something, then it should show
"origin/something" and it already does).

* jh/shorten-refname:
  t1514: refname shortening is done after dereferencing symbolic refs
  shorten_unambiguous_ref(): Fix shortening refs/remotes/origin/HEAD to origin
  t1514: Demonstrate failure to correctly shorten "refs/remotes/origin/HEAD"
  t1514: Add tests of shortening refnames in strict/loose mode
Merge branch 'jk/gitweb-utf8' into pu

Various fixes to gitweb.

Drew Northup volunteered to take a look into this.
$gmane/226216

* jk/gitweb-utf8:
  gitweb: Fix broken blob action parameters on blob/commitdiff pages
  gitweb: Don't append ';js=(0|1)' to external links
  gitweb: Make feed title valid utf8
  gitweb: Fix utf8 encoding for blob_plain, blobdiff_plain, commitdiff_plain, and patch
Merge branch 'jc/format-patch' into pu

A new option to send a single patch to the standard output to be
appended at the bottom of a message.  I personally have no need for
this, but it was easy enough to cobble together.  Tests, docs and
stripping out more MIMEy stuff are left as exercises to interested
parties.

tying its loose ends.

* jc/format-patch:
  format-patch: --inline-single
  format-patch: rename "no_inline" field

Merge branch 'rr/triangle-push-fix' into pu

triangular workflow where it does not quite apply.

Will be worked further.

  t/push-default: generalize test_push_{success, commit}
  push: make upstream, simple work with pushdefault
  t/push-default: remove redundant test_config lines
