2c0b4dfd5a combine-diff.c: type sanity.
In diff_tree_combined(), show_log_first boolean is initialized with
rev->loginfo (pointer to a string); the intention is that if we have
some string to be emitted we would want to remember that fact.  Picky
compilers are offended by this, so make the expression a bit type-safer.

2386c2975d combine-diff.c: type sanity
- combine_diff() took cnt (count) which is unsigned in nature but the
  parameter type was declared as "int";
- find_next() took "uninteresting" parameter, which masked a static
  function of the same name;
- show_parent_lno() took an unused parameter "cnt";
- show_patch_diff() used a local variable in nested inner scope with
  the same name with different type, masking the one in the outer scope;
- the last loop in show_patch_diff iterated over lines so it should use
  the local variable "lno"

3969cf7db1 Fix some more diff options changes.
This fixes various problems in the new diff options code.

 - Fix --cc/-c --patch; it showed two-tree diff used internally.

 - Use "---\n" only where it matters -- that is, use it
   immediately after the commit log text when we show a
   commit log and something else before the patch text.

 - Do not output spurious extra "\n"; have an extra newline
   after the commit log text always when we have diff output and
   we are not doing oneline.

 - When running a pickaxe you need to go recursive.

ee1e5412a7 git diff: support "-U" and "--unified" options properly
We used to parse "-U" and "--unified" as part of the GIT_DIFF_OPTS
environment variable, but strangely enough we would _not_ parse them as
part of the normal diff command line (where we only accepted "-u").

This adds parsing of -U and --unified, both with an optional numeric
argument. So now you can just say

	git diff --unified=5

to get a unified diff with a five-line context, instead of having to do
something silly like

	GIT_DIFF_OPTS="--unified=5" git diff -u

(that silly format does continue to still work, of course).

"git diff(n) tree0 tree1 tree2...treeN" does combined diff that
shows a merge of tree1..treeN to result in tree0.

965f803c32 combine-diff: show diffstat with the first parent.
Asking for stat (either with --stat or --patch-with-stat) gives
you diffstat for the first parent, even under combine-diff.

While the combined patch is useful to highlight the complexity
and interaction of the parts touched by all branches when
reviewing a merge commit, diffstat is a tool to assess the
extent of damage the merge brings in, and showing stat with the
first parent is more sensible than clever per-parent diffstat.

eab144ac49 Log message printout cleanups (#2)
Here's a further patch on top of the previous one with cosmetic
improvements (no "real" code changes, just trivial updates):

 - it gets the "---" before a diffstat right, including for the combined
   merge case. Righ now the logic is that we always use "---" when we have
   a diffstat, and an empty line otherwise. That's how I visually prefer
   it, but hey, it can be tweaked later.

 - I made "diff --cc/combined" add the "---/+++" header lines too. The
   thing won't be mistaken for a valid diff, since the "@@" lines have too
   many "@" characters (three or more), but it just makes it visually
   match a real diff, which at least to me makes a big difference in
   readability. Without them, it just looks very "wrong".

   I guess I should have taken the filename from each individual entry
   (and had one "---" file per parent), but I didn't even bother to try to
   see how that works, so this was the simple thing.

With this, doing a

	git log --cc --patch-with-stat

looks quite readable, I think. The only nagging issue - as far as I'm
concerned - is that diffstats for merges are pretty questionable the way
they are done now. I suspect it would be better to just have the _first_
diffstat, and always make the merge diffstat be the one for "result
against first parent".

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.

The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like

	if (rev->logopt)
		show_log(rev, rev->logopt, "---\n");

but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.

That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:

	while ((commit = get_revision(rev)) != NULL) {
		log_tree_commit(rev, commit);
		free(commit->buffer);
		commit->buffer = NULL;
	}

so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.

I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.

This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.

d416df8869 combine-diff: Record diff status a bit more faithfully

The diff-raw output for combined diff is made a bit uglier by

case you would see "MM" in the output, an Evil Merge that
touches a path that was added by inheriting from one parent is
possible and it would be shown like these:

ee63802422 diff-tree -c raw output
NOTE! This makes "-c" be the default, which effectively means that merges 
are never ignored any more, and "-m" is a no-op. So it changes semantics.

I would also like to make "--cc" the default if you do patches, but didn't 
actually do that.

The raw output format is not wonderfully pretty, but it's distinguishable 
from a "normal patch" in that a normal patch with just one parent has just 
one colon at the beginning, while a multi-parent raw diff has <n> colons 
for <n> parents.

So now, in the kernel, when you do

	git-diff-tree cce0cac125623f9b68f25dd1350f6d616220a8dd

(to see the manual ARM merge that had a conflict in arch/arm/Kconfig), you 
get

	cce0cac125623f9b68f25dd1350f6d616220a8dd
	::100644 100644 100644 4a63a8e2e45247a11c068c6ed66c6e7aba29ddd9 77eee38762d69d3de95ae45dd9278df9b8225e2c 2f61726d2f4b636f6e66696700dbf71a59dad287       arch/arm/Kconfig

ie you see two colons (two parents), then three modes (parent modes 
followed by result mode), then three sha1s (parent sha1s followed by
result sha1).

Which is pretty close to the normal raw diff output.

Cool/stupid exercise:

	$ git-whatchanged | grep '^::' | cut -f2- | sort |
	  uniq -c | sort -n | less -S

will show which files have needed the most file-level merge conflict
resolution. Useful? Probably not. But kind of interesting.

fd4b1d2193 combine-diff: add safety check to --cc.
The earlier change implemented "only two version" check but
without checking if the change rewrites from all the parents.
This implements a check to make sure that a change introduced
by the merge from all the parents is caught to be interesting.

bf1c32bdec combine-diff: update --cc "uninteresting hunks" logic.
Earlier logic was discarding hunks that has difference from only
one parent or the same difference from all but one parent.  This
changes it to check if the differences on all lines are from the
same sets of parents.  This discards more uninteresting hunks
and seems to match expectations more naturally.

3c39e9bdeb combine-diff: reuse diff from the same blob.
When dealing with an insanely large Octopus, it is possible to
optimize by noticing that more than one parents have the same
blob and avoid running diff between a parent and the merge
result by reusing an earlier result.

ea726d02e9 diff-files: -c and --cc options.
This ports the "combined diff" to diff-files so that differences
to the working tree files since stage 2 and stage 3 are shown
the same way as combined diff output from diff-tree for the
merge commit would be shown if the current working tree files
are committed.

3ec1909fda combine-diff: better hunk splitting.
It considered an otherwise unchanged line that had line removals
in front of it an interesting line, which caused hunks to have
one extra the trailing context line.

8828cdcb44 diff-tree --cc: squelch header generation on empty patch.
Earlier round showed the commit log header and "diff --combined"
header even for paths that had no interesting hunk under --cc
flag.  Move the header display logic around to squelch them.
With this, a merge that does not have any interesting merges
will not be shown with --cc option, unless -m is used at the
same time.
