Merge branch 'nd/push-no-thin'

"git push --no-thin" was a no-op by mistake.

* nd/push-no-thin:
  push: respect --no-thin
Merge branch 'sh/pull-rebase-preserve'

"git pull --rebase" always flattened the history; pull.rebase can
now be set to "preserve" to invoke "rebase --preserve-merges".

* sh/pull-rebase-preserve:
  pull: allow pull to preserve merges when rebasing
Merge branch 'jn/post-receive-utf8'

Update post-receive-email script to make sure the message contents
and pathnames are encoded consistently in UTF-8.

* jn/post-receive-utf8:
  hooks/post-receive-email: set declared encoding to utf-8
  hooks/post-receive-email: force log messages in UTF-8
  hooks/post-receive-email: use plumbing instead of git log/show
Merge branch 'es/rebase-i-respect-core-commentchar'

"rebase -i" forgot that the comment character can be configurable
while reading its insn sheet.

  rebase -i: fix cases ignoring core.commentchar
Merge branch 'js/xread-in-full'

A call to xread() was used without a loop around to cope with short
read in the codepath to stream new contents to a pack.

* js/xread-in-full:
  stream_to_pack: xread does not guarantee to read all requested bytes
Merge branch 'sb/mailmap-freeing-NULL-is-ok'

Merge branch 'tf/gitweb-ss-tweak'

Tweak Gitweb CSS to layout some elements better.

* tf/gitweb-ss-tweak:
  gitweb: make search help link less ugly
  gitweb: omit the repository owner when it is unset
  gitweb: vertically centre contents of page footer
  gitweb: ensure OPML text fits inside its box
Merge branch 'rt/rebase-p-no-merge-summary'

"git rebase -p" internally used the merge machinery, but when
rebasing, there should not be a need for merge summary.

* rt/rebase-p-no-merge-summary:
  rebase --preserve-merges: ignore "merge.log" config
Merge branch 'es/rebase-i-no-abbrev'

The commit object names in the insn sheet that was prepared at the
beginning of "rebase -i" session can become ambiguous as the
rebasing progresses and the repository gains more commits. Make
sure the internal record is kept with full 40-hex object names.

* es/rebase-i-no-abbrev:
  rebase -i: fix short SHA-1 collision
  t3404: rebase -i: demonstrate short SHA-1 collision
  t3404: make tests more self-contained
Merge branch 'jc/ls-files-killed-optim'

"git ls-files -k" needs to crawl only the part of the working tree
that may overlap the paths in the index to find killed files, but
shared code with the logic to find all the untracked files, which
made it unnecessarily inefficient.

* jc/ls-files-killed-optim:
  dir.c::test_one_path(): work around directory_exists_in_index_icase() breakage
  t3010: update to demonstrate "ls-files -k" optimization pitfalls

reset: handle submodule with trailing slash

When using tab-completion, a directory path will often end with a
trailing slash which currently confuses "git reset" when dealing with
submodules.  Now that we have parse_pathspec we can easily handle this
by simply adding the PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag.

To do this, we need to move the read_cache() call before the
parse_pathspec() call.  All of the existing paths through cmd_reset()
that do not die early already call read_cache() at some point, so there
is no performance impact to doing this in the common case.

pathspec: use is_dir_sep() to check for trailing slashes

This allows us to correctly removing trailing backslashes on Windows
when checking for submodules.

pathspec: strip multiple trailing slashes from submodules

In PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP, change the logic to remove
multiple trailing directory separators from the path to submodules.
This allows us to replace the submodule path trailing slash removal in
builtin/rm.c with the PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag to
parse_pathspec() without changing the behaviour of trailing slashes.

rm: re-use parse_pathspec's trailing-slash removal

Instead of re-implementing the "remove trailing slashes" loop in
builtin/rm.c just pass PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP to
parse_pathspec.
