This is a nice change, available because of lack of backward
compatibility with v1. The porcelain v2 format branch-related
information could be enhanced without risk of breaking parsers,
or having new information put at the end even if it does not fit
there (like in previous iteration).
One thing that can serve as goal for the series is using the
question: would it make __git_ps1() from git-prompt.sh be able
to render fully decorated prompt with all bells and whistles,
and with all combinations of options. Thus beside upstream
in the future we might want SVN upstream, and/or pushed-to
remote branch (and remote push upstream repository), etc.
But that's for the future (and it is possible for the future)...
Yes, I was hoping to be able to simplify and/or speed up
__git_ps1() with this data. "Namespacing" the branch data
here. And then later add the state data (in a merge,
in a rebase, and etc.) in a series of "# state.*" headers.
And so on, until we get everything that __git_ps1() needs.
However, to really make that work, we might want to add
a --no-scan (or minimial scan) option, to just return the
header data, since __git_ps1() doesn't care about the list
of changes.

A question: do unmerged entries always have only one single filename?
Or unmerged entries are always only about CONFLICT(contents), and no
other?
As far as I could tell, unmerged rename conflicts appear with a single
filename.
When I did a divergent rename (in both branches), merge creates
a stage-1 "DD" entry,
a stage-2 "AU" entry, and
a stage-3 with a "UA" entry.
Status reports it as 3 rows.
When I did a rename in one branch and an edits in both, merge
creates: either a "DU" or "UD" conflict (depending on the direction
of the merge).
Given that the index is ordered and accessed by path (and there is
no pathname field in a cache entry to link it to a different one),
I have to say that this is true.
Would a note (or a link to other documentation) about octopus merges
be out of place here?
I put a note in the code about it reporting the last entry at each
stage that are present in the index, but I'm not sure about how much
we want to say here.
If octopus finds conflicts, the worktree will probably be in a
funky state anyway.

+A series of lines are then displayed for untracked and ignored entries.
+
+ <x> <path>
+
+Where <x> is "?" for untracked entries and "!" for ignored entries.
A question: are they displayed in that order, i.e. first all untracked,
then all ignored, or it is something one cannot rely about?
With the unique prefix character it shouldn't matter. I do print
all the '?' lines first then all the '!' lines, so the manpage
could be clarified if we wanted. I was just trying to save another
paragraph in the manpage.
+
+In all 3 line formats, pathnames will be "C Quoted" if they contain
"C Quoted" or "C-Quoted"? How it is described in other places of
the Git documentation?
I was probably inconsistent, I think it should be "c-quoted" (with the
hypen) providing we like this term.
Each of the git-diff*.txt and diff-format.txt files talk about
this quoting scheme, but none give it an explicit name.
+any of the following characters: TAB, LF, double quotes, or backslashes.
+These characters will be replaced with \t, \n, \", and \\, respectively,
+and the pathname will be enclosed in double quotes.
+
+When the `-z` option is given, a NUL (zero) byte follows each pathname;
+serving as both a separator and line termination. No pathname quoting
+or backslash escaping is performed. All fields are output in the same
+order.
Does it mean that
2 [...] <cq-path>\t<cq-pathSrc>\n
line (including line terminator) is replaced with
2 [...] <path>\0<pathSrc>\0
that is, it replaces a separator (TAB, "\t") and line termination (LF, "\n");
here spelled in full?
Yes. Let me try to clarify that in the manpage.
Thanks,
Jeff
