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

"git mv A B" when moving a submodule A does "the right thing",
inclusing relocating its working tree and adjusting the paths in
the .gitmodules file.

  Teach mv to update the path entry in .gitmodules for moved submodules

Merge branch 'jk/remote-helper-with-signed-tags' into pu

Allows remote-helpers to declare they can handle signed tags, and
issue a warning when using those that don't.

There were some comments on the noisiness of the warning output,
but it appears that everybody involved in the area is basically
happy with the direction this series goes in?

* jk/remote-helper-with-signed-tags:
  transport-helper: add 'signed-tags' capability
  transport-helper: pass --signed-tags=warn-strip to fast-export
  fast-export: add --signed-tags=warn-strip mode

# Conflicts:
# 	t/t5801-remote-helpers.sh
Merge branch 'jn/config-ignore-inaccessible' into pu

When $HOME is misconfigured to point at an unreadable directory, we
used to complain and die. This loosens the check.

I do not think we agreed that this is a good idea, though.

* jn/config-ignore-inaccessible:
  config: allow inaccessible configuration under $HOME
Merge branch 'jn/gitweb-install-doc' into pu

Reword gitweb configuration instrutions.

Merge branch 'kb/status-ignored-optim-2' into pu

Rerolls kb/status-ignored-optim topic (reverted from 'next').  Not
merged to 'pu' as it heavily interferes with as/check-ignore topic.
