When "add -p" sees an unmerged entry, it shows the combined
diff and then immediately skips the hunk. This can be
confusing in a variety of ways, depending on whether there
are other changes to stage (in which case you get the
superfluous combined diff output in between other hunks) or
not (in which case you get the combined diff and the program
exits immediately, rather than seeing "No changes").
The current behavior was not planned, and is just what the
implementation happens to do. Instead, let's explicitly
remove unmerged entries from our list of modified files, and
print a warning that we are ignoring them.
We can cheaply find which entries are unmerged by adding
"--raw" output to the "diff-files --numstat" we already run.
There is one non-obvious thing we must change when parsing
this combined output. Before this patch, when we saw a
numstat line for a file that did not have index changes, we
would create a new record with 'unchanged' in the 'INDEX'
field. Because "--raw" comes before "--numstat", we must
move this special-case down to the raw-line case (and it is
sufficient to move it rather than handle it in both places,
since any file which has a --numstat will also have a --raw
entry).

A broken here-document was not caught because end of file is taken by
an implicit end of the here document (POSIX does not seem to say it is
an error to lack the delimiter), and everything in the test just turned
into a single "cat into a file".

Arnaud Lacombe reported that with the recent change to reject overlapping

feeds overlapping hunks without coalescing adjacent ones claim that the
patch does not apply. Expose the problem to be fixed.

Commit 24ab81a fixed the deletion of empty files, but broke
deletion of non-empty files. The approach it took was to
factor out the "deleted" line from the patch header into its
own hunk, the same way we do for mode changes. However,
unlike mode changes, we only showed the special "delete this
file" hunk if there were no other hunks. Otherwise, the user
would annoyingly be presented with _two_ hunks: one for
deleting the file and one for deleting the content.
This meant that in the non-empty case, we forgot about the
deleted line entirely, and we submitted a bogus patch to
git-apply (with "/dev/null" as the destination file, but not
marked as a deletion).
Instead, this patch combines the file deletion hunk and the
content deletion hunk (if there is one) into a single
deletion hunk which is either staged or not.

Usually we show deletion as a big hunk deleting all of the
file's text. However, for files with no content, the diff
shows just the 'deleted file mode ...' line. This patch
cause "add -p" (and related commands) to recognize that line
and explicitly ask about deleting the file.
We only add the "stage this deletion" hunk for empty files,
since other files will already ask about the big content
deletion hunk. We could also change those files to simply
display "stage this deletion", but showing the actual
deleted content is probably what an interactive user wants.

In 0392513 (add-interactive: refactor mode hunk handling, 2009-04-16),
we merged the interaction loops for mode changes and hunk staging.
This was fine at the time, because 0beee4c (git-add--interactive:
remove hunk coalescing, 2008-07-02) removed hunk coalescing.
However, in 7a26e65 (Revert "git-add--interactive: remove hunk
coalescing", 2009-05-16), we resurrected it. Since then, the code
would attempt in vain to merge mode changes with diff hunks,
corrupting both in the process.
We add a check to the coalescing loop to ensure it only looks at diff
hunks, thus skipping mode changes.

Adds a new option 'e' to the 'add -p' command loop that lets you edit
the current hunk in your favourite editor.
If the resulting patch applies cleanly, the edited hunk will
immediately be marked for staging. If it does not apply cleanly, you
will be given an opportunity to edit again. If all lines of the hunk
are removed, then the edit is aborted and the hunk is left unchanged.
Applying the changed hunk(s) relies on Johannes Schindelin's new
--recount option for git-apply.
Note that the "real patch" test intentionally uses
(echo e; echo n; echo d) | git add -p
even though the 'n' and 'd' are superfluous at first sight. They
serve to get out of the interaction loop if git add -p wrongly
concludes the patch does not apply.

When using the 'p'atch command, instead of just throwing out any mode

When a path is examined in the patch subcommand, any mode changes in
the file are given to use in the diff header by git-diff. If no hunks
are staged, then we throw out that header and do not touch the
path. But if _any_ hunks are staged, we use the header, and the mode
is changed together with the contents.
Since the 'p'atch command should just be dealing with hunks that are
shown to the user, it makes sense to just ignore mode changes
entirely. We do squirrel away the mode, though, since the next patch
will allow users to select the mode update separately.

Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.
This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".
On systems with a less-capable diff, you can do:
GIT_TEST_CMP=cmp make test

There were several points where we looked at the HEAD
commit; for initial commits, this is meaningless. So instead
we:
- show staged status data as a diff against the empty tree
instead of HEAD
- show file diffs as creation events
- use "git rm --cached" to revert instead of going back to
the HEAD commit
We magically reference the empty tree to implement this.
