78cc1a540b Revert "diff-lib.c: adjust position of i-t-a entries in diff"
This reverts commit d95d728aba.

It turns out that many other commands that need to interact with the
result of running diff-files and diff-index, e.g.  "git apply", "git
rm", etc., need to be adjusted to the new world order it brings in.
For example, it would break this sequence to correct a whitespace
breakage in the parts you changed:

	git add -N file
	git diff --cached file | git apply --cached --whitespace=fix
	git checkout file

In the old world order, "diff" showed a patch to modify an existing
empty file by adding its full contents, and "apply" updated the
index by modifying the existing empty blob (which is what an
Intent-to-Add entry records in the index) with that patch.

In the new world order, "diff" shows a patch to create a new file
with its full contents, but because "apply" thinks that the i-t-a
entry already exists in the index, it refused to accept a creation.

Adjusting "apply" to this new world order is easy, but we need to
assess the extent of the damage to the rest of the system the new
world order brought in before going forward and adjust them all,
after which we can resurrect the commit being reverted here.

d95d728aba diff-lib.c: adjust position of i-t-a entries in diff
Entries added by "git add -N" are reminder for the user so that they
don't forget to add them before committing. These entries appear in
the index even though they are not real. Their presence in the index
leads to a confusing "git status" like this:

    On branch master
    Changes to be committed:
            new file:   foo

    Changes not staged for commit:
            modified:   foo

If you do a "git commit", "foo" will not be included even though
"status" reports it as "to be committed". This patch changes the
output to become

    On branch master
    Changes not staged for commit:
            new file:   foo

    no changes added to commit

The two hunks in diff-lib.c adjust "diff-index" and "diff-files" so
that i-t-a entries appear as new files in diff-files and nothing in
diff-index.

Due to this change, diff-files may start to report "new files" for the
first time. "add -u" needs to be told about this or it will die in
denial, screaming "new files can't exist! Reality is wrong." Luckily,
it's the only one among run_diff_files() callers that needs fixing.

Now in the new world order, a hierarchy in the index that contain
i-t-a paths is written out as a tree object as if these i-t-a
entries do not exist, and comparing the index with such a tree
object that would result from writing out the hierarchy will result
in no difference.  Update a test in t2203 that expected the i-t-a
entries to appear as "added to the index" in the comparison to
instead expect no output.

An earlier change eec3e7e4 (cache-tree: invalidate i-t-a paths after
generating trees, 2012-12-16) becomes an unnecessary pessimization
in the new world order---a cache-tree in the index that corresponds
to a hierarchy with i-t-a paths can now be marked as valid and
record the object name of the tree that results from writing a tree
object out of that hierarchy, as it will compare equal to that tree.

Reverting the commit is left for the future, though, as it is purely
a performance issue and no longer affects correctness.

4b06318664 branch: name detached HEAD analogous to status
"git status" carefully names a detached HEAD "at" resp. "from" a rev or
ref depending on whether the detached HEAD has moved since. "git branch"
always uses "from", which can be confusing, because a status-aware user
would interpret this as moved detached HEAD.

Make "git branch" use the same logic and wording.

06c21e18ab cmd_push: pass "flags" pointer to config callback
This will let us manipulate any transport flags which have matching
config options (there are none yet, but we will add one in
the next patch).

We could also just make "flags" a static file-scope global,
but the result is a little confusing. We end up passing it
along through do_push and push_with_options, each of which
further munge it. Having slightly-differing versions of the
flags variable available to those functions would probably
cause more confusion than it is worth. Let's just keep the
original local to cmd_push, and it can continue to pass it
through the call-stack.
