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 '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.

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).

* jh/shorten-refname:
  t1514: refname shortening is done after dereferencing symbolic refs
  shorten_unambiguous_ref(): Fix shortening refs/remotes/origin/HEAD to origin

Merge branch 'jk/gitweb-utf8' into pu

Various fixes to gitweb.

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

  gitweb: Fix broken blob action parameters on blob/commitdiff pages
  gitweb: Don't append ';js=(0|1)' to external links

  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()
  show-ref.c: Add missing call to git_config()
Merge branch 'tr/merge-recursive-index-only' into pu

Will hold, until we get any user.

  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()
