Merge branch 'jc/reflog-doc' into pu

Document rules to use GIT_REFLOG_ACTION variable in the scripted
Porcelain.  git-rebase--interactive locally violates this, but it
is a leaf user that does not call out to or dot-sources other
scripts, so fixing it is not all that urgent.

* jc/reflog-doc:
  setup_reflog_action: document the rules for using GIT_REFLOG_ACTION

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; kicked 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

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).

Merge branch 'jk/gitweb-utf8' into pu

Various fixes to gitweb.

Drew Northup volunteered to take a look into this.

* 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.

Merge branch 'rj/read-default-config-in-show-ref-pack-refs' into pu

The changes themselves are probably good, but it is unclear what
basic setting needs to be read for which exact operation.

$gmane/228294

* rj/read-default-config-in-show-ref-pack-refs:
  ### DONTMERGE: needs better explanation on what config they need
  pack-refs.c: Add missing call to git_config()

Merge branch 'tr/merge-recursive-index-only' into pu

Will hold, until we get any user.

* tr/merge-recursive-index-only:
  merge-recursive: -Xindex-only to leave worktree unchanged
  merge-recursive: untangle double meaning of o->call_depth
  merge-recursive: remove dead conditional in update_stages()
Merge branch 'dw/diff-no-index-doc' into pu

When the user types "git diff" outside a working tree, thinking he
is inside one, the current error message that is a single-liner
"usage: git diff --no-index <path> <path>" may not be sufficient to
make him realize the mistake. Add "Not a git repository" to the
error message when we fell into the "--no-index" mode without an
explicit command line option to instruct us to do so.

* dw/diff-no-index-doc:
  diff --no-index: describe in a separate paragraph
  diff --no-index: clarify operation when not inside a repository

Merge branch 'cc/replace-with-the-same-type' into pu

Using the replace mechanism to swap an object with another object
of a different type can introduce inconsistency (e.g. a tree
expects an object name to refer to a blob, but the blob object can
be mistakenly or maliciously replaced with an object with a
different type). Attempt to forbid such.

This may need to be given an escape hatch "--force", though.

* cc/replace-with-the-same-type:
  Documentation/replace: add Creating Replacement Objects section
  t6050-replace: add test to clean up all the replace refs
  t6050-replace: test that objects are of the same type
  Documentation/replace: state that objects must be of the same type
  replace: forbid replacing an object with one of a different type
Merge branch 'jx/clean-interactive' into pu

Finishing touches to update the document to adjust to a new option
"git clean" learned recently.

* jx/clean-interactive:
  documentation: clarify notes for clean.requireForce
Merge branch 'mm/status-without-comment-char' into pu

Allow "git status" to omit the prefix to make its output a comment
in a commit log editor, which is not necessary for human
consumption.

* mm/status-without-comment-char:
  status: introduce status.displayCommentChar to disable display of #
  SQUASH: do not fprintf() random strings
