Merge branch 'mh/fetch-tags-in-addition-to-normal-refs' into pu

Some questionable paragraphs in the doc updates, but other than
that looks reasonably solid.

* mh/fetch-tags-in-addition-to-normal-refs:
  fetch, remote: properly convey --no-prune options to subprocesses
  builtin/remote.c:update(): use struct argv_array
  builtin/remote.c: reorder function definitions
  query_refspecs(): move some constants out of the loop
  fetch --prune: prune only based on explicit refspecs
  SQUASH??? --tags is no longer a short-hand
  fetch --tags: fetch tags *in addition to* other stuff
  builtin/fetch.c: reorder function definitions
  ref_remove_duplicates(): improve documentation comment
  ref_remove_duplicates(): simplify function
  ref_remove_duplicates(): avoid redundant bisection
  get_ref_map(): rename local variables
  api-remote.txt: correct section "struct refspec"
  t5510: check that "git fetch --prune --tags" does not prune branches
  t5510: prepare test refs more straightforwardly
  t5510: use the correct tag name in test
Merge branch 'jc/ref-excludes' into pu

People often wished a way to tell "git log --branches" (and "git
log --remotes --not --branches") to exclude some local branches
from the expansion of "--branches" (similarly for "--tags", "--all"
and "--glob=<pattern>").  Now they have one.

* jc/ref-excludes:
  document --exclude option
  revision: introduce --exclude=<glob> to tame wildcards
Merge branch 'rv/send-email-cache-generated-mid' into pu

* rv/send-email-cache-generated-mid:
  git-send-email: Cache generated message-ids, use them when prompting
  git-send-email: add optional 'choices' parameter to the ask sub
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.

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

# Conflicts:
# 	builtin/log.c
# 	log-tree.c
# 	pretty.c
Merge branch 'jc/show-branch' into pu

* jc/show-branch:
  show-branch: use commit slab to represent bitflags of arbitrary width
  show-branch.c: remove "all_mask"
  show-branch.c: abstract out "flags" operation
  show-branch.c: lift all_mask/all_revs to a global static
  show-branch.c: update comment style

# Conflicts:
# 	builtin/show-branch.c
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

Holding until there is a caller to learn from.

* 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 'yt/shortened-rename' into pu

Attempts to give more weight on the fact that a filepair represents
a rename than showing substring of the actual path when diffstat
lines are not wide enough.

I am not sure if that is solving a right problem, though.

* yt/shortened-rename:
  SQUASH??? style fixes and s/omit/shorten/ where appropriate
  diff.c: keep arrow(=>) on show_stats()'s shortened filename part to make rename visible
Merge branch 'jk/pack-bitmap' into pu

* jk/pack-bitmap:
