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.

* jc/format-patch:
  format-patch: --inline-single
  format-patch: rename "no_inline" field
Merge branch 'mg/qnx6' into pu

Still under discussion.

* mg/qnx6:
  QNX: newer QNX 6.x.x is not so crippled
Merge branch 'mb/gitweb-highlight-link-target' into pu

$gmane/211935

* mb/gitweb-highlight-link-target:
  Highlight the link target line in Gitweb using CSS
Merge branch 'mb/remote-default-nn-origin' into pu

When the user does not specify what remote to interact with, we
often attempt to use 'origin'.  This can now be customized via a
configuration variable.

$gmane/210151

"The first remote becomes the default" bit is better done as a
separate step.

* mb/remote-default-nn-origin:
  Teach get_default_remote to respect remote.default.
  Test that plain "git fetch" uses remote.default when on a detached HEAD.
  Teach clone to set remote.default.
  Teach "git remote" about remote.default.
  Teach remote.c about the remote.default configuration setting.
  Rename remote.c's default_remote_name static variables.

# Conflicts:
# 	builtin/remote.c
# 	t/t5505-remote.sh
Merge branch 'hv/config-from-strbuf' into pu

$gmane/217811

* hv/config-from-strbuf:
  teach config parsing to read from strbuf
  config: make parsing stack struct independent from actual data source
  config: drop file pointer validity check in get_next_char()
  config: factor out config file stack management
Merge branch 'po/help-guides' into pu

Give more visibility to "concept guides" to help "git help" users.

$gmane/217384

* po/help-guides:
  help doc: include --guide option description
  help.c: add list_common_guides_help() function
  help.c: add --guide option
  help.c: use OPT_COUNTUP
  show 'git help <guide>' usage, with examples
Merge branch 'jc/merge-tag-object' into pu

"git merge $(git rev-parse v1.8.2)" behaved quite differently from
"git merge v1.8.2" as if v1.8.2 were written as v1.8.2^0 and did
not pay much attention to the annotated tag payload.

This makes the code notice the type of the tag object, in addition
to the dwim_ref() based classification the current code uses
(i.e. the name appears in refs/tags/) to decide when to special
case merging of tags.

We may actually want to call the current behaviour a feature,
though.  After all, the user went to great length to feed something
different from the normal "v1.8.2" to the command.

* jc/merge-tag-object:
  merge: a random object may not necssarily be a commit
Merge branch 'jn/push-tests' into pu

Update t5516 with style fixes.

* jn/push-tests:
  push test: rely on &&-chaining instead of 'if bad; then echo Oops; fi'
  push test: simplify check of push result
  push test: use test_config when appropriate

# Conflicts:
# 	t/t5516-fetch-push.sh
Merge branch 'jk/index-pack-correct-depth-fix' into pu

"index-pack --fix-thin" used uninitialize value to compute delta
depths of objects it appends to the resulting pack.

* jk/index-pack-correct-depth-fix:
  index-pack: always zero-initialize object_entry list
Merge branch 'nd/index-pack-threaded-fixes' into pu

"index-pack --verify-stat" used a few counters outside protection
of mutex, possibly showing incorrect numbers.

* nd/index-pack-threaded-fixes:
  index-pack: guard nr_resolved_deltas reads by lock
  index-pack: protect deepest_delta in multithread code
Merge branch 'rr/tests-dedup-test-config' into pu

* rr/tests-dedup-test-config:
  t4018,7810,7811: remove test_config() redefinition

  dir.c: unify is_excluded and is_path_excluded APIs
  dir.c: move prep_exclude and factor out parts of last_exclude_matching
