Merge branch 'jh/status-v2-porcelain'

Browse Source 
Enhance "git status --porcelain" output by collecting more data on
the state of the index and the working tree files, which may
further be used to teach git-prompt (in contrib/) to make fewer
calls to git.

* jh/status-v2-porcelain:
  status: unit tests for --porcelain=v2
  test-lib-functions.sh: add lf_to_nul helper
  git-status.txt: describe --porcelain=v2 format
  status: print branch info with --porcelain=v2 --branch
  status: print per-file porcelain v2 status data
  status: collect per-file data for --porcelain=v2
  status: support --porcelain[=<version>]
  status: cleanup API to wt_status_print
  status: rename long-format print routines

characters are not specially formatted; no quoting or
backslash-escaping is performed.
Porcelain Format Version 2
~~~~~~~~~~~~~~~~~~~~~~~~~~
Version 2 format adds more detailed information about the state of
the worktree and changed items. Version 2 also defines an extensible
set of easy to parse optional headers.
Header lines start with "#" and are added in response to specific
command line arguments. Parsers should ignore headers they
don't recognize.
### Branch Headers
If `--branch` is given, a series of header lines are printed with
information about the current branch.
Line Notes
------------------------------------------------------------
# branch.oid <commit> | (initial) Current commit.
# branch.head <branch> | (detached) Current branch.
# branch.upstream <upstream_branch> If upstream is set.
# branch.ab +<ahead> -<behind> If upstream is set and
the commit is present.
------------------------------------------------------------
### Changed Tracked Entries
Following the headers, a series of lines are printed for tracked
entries. One of three different line formats may be used to describe
an entry depending on the type of change. Tracked entries are printed
in an undefined order; parsers should allow for a mixture of the 3
line types in any order.
Ordinary changed entries have the following format:
1 <XY> <sub> <mH> <mI> <mW> <hH> <hI> <path>
Renamed or copied entries have the following format:
2 <XY> <sub> <mH> <mI> <mW> <hH> <hI> <X><score> <path><sep><origPath>
Field Meaning
--------------------------------------------------------
<XY> A 2 character field containing the staged and
unstaged XY values described in the short format,
with unchanged indicated by a "." rather than
a space.
<sub> A 4 character field describing the submodule state.
"N..." when the entry is not a submodule.
"S<c><m><u>" when the entry is a submodule.
<c> is "C" if the commit changed; otherwise ".".
<m> is "M" if it has tracked changes; otherwise ".".
<u> is "U" if there are untracked changes; otherwise ".".
<mH> The octal file mode in HEAD.
<mI> The octal file mode in the index.
<mW> The octal file mode in the worktree.
<hH> The object name in HEAD.
<hI> The object name in the index.
<X><score> The rename or copy score (denoting the percentage
of similarity between the source and target of the
move or copy). For example "R100" or "C75".
<path> The pathname. In a renamed/copied entry, this
is the path in the index and in the working tree.
<sep> When the `-z` option is used, the 2 pathnames are separated
with a NUL (ASCII 0x00) byte; otherwise, a tab (ASCII 0x09)
byte separates them.
<origPath> The pathname in the commit at HEAD. This is only
present in a renamed/copied entry, and tells
where the renamed/copied contents came from.
--------------------------------------------------------
Unmerged entries have the following format; the first character is
a "u" to distinguish from ordinary changed entries.
u <xy> <sub> <m1> <m2> <m3> <mW> <h1> <h2> <h3> <path>
Field Meaning
--------------------------------------------------------
<XY> A 2 character field describing the conflict type
as described in the short format.
<sub> A 4 character field describing the submodule state
as described above.
<m1> The octal file mode in stage 1.
<m2> The octal file mode in stage 2.
<m3> The octal file mode in stage 3.
<mW> The octal file mode in the worktree.
<h1> The object name in stage 1.
<h2> The object name in stage 2.
<h3> The object name in stage 3.
<path> The pathname.
--------------------------------------------------------
### Other Items
Following the tracked entries (and if requested), a series of
lines will be printed for untracked and then ignored items
found in the worktree.
Untracked items have the following format:
? <path>
Ignored items have the following format:
! <path>
### Pathname Format Notes and -z
When the `-z` option is given, pathnames are printed as is and
without any quoting and lines are terminated with a NUL (ASCII 0x00)
byte.
Otherwise, all pathnames will be "C-quoted" if they contain any tab,
linefeed, double quote, or backslash characters. In C-quoting, these
characters will be replaced with the corresponding C-style escape
sequences and the resulting pathname will be double quoted.
