ab5f42422d merge-tree: fix typo in "both changed identically"
Commit aacecc3 (merge-tree: don't print entries that match "local" -
2013-04-07) had a typo causing the "same in both" check to be incorrect
and check if both the base and "their" versions are removed instead of
checking that both the "our" and "their" versions are removed.  Fix
this.

aacecc3b36 merge-tree: don't print entries that match "local"
The documentation says:

	the output from the command omits entries that match the
	<branch1> tree.

But currently "added in branch1" and "removed in branch1" (both while
unchanged in branch2) do print output.  Change this so that the
behaviour matches the documentation.

35ffe75831 merge-tree: fix d/f conflicts
The previous commit documented two known breakages revolving around
a case where one side flips a tree into a blob (or vice versa),
where the original code simply gets confused and feeds a mixture of
trees and blobs into either the recursive merge-tree (and recursing
into the blob will fail) or three-way merge (and merging tree contents
together with blobs will fail).

Fix it by feeding trees (and only trees) into the recursive
merge-tree machinery and blobs (and only blobs) into the three-way
content level merge machinery separately; when this happens, the
entire merge has to be marked as conflicting at the structure level.

8dd15c6a90 merge-tree: add comments to clarify what these functions are doing
Rename the "branch1" parameter given to resolve() to "ours", to
clarify what is going on.  Also, annotate the unresolved_directory()
function with some comments to show what decisions are made in each
step, and highlight two bugs that need to be fixed.

Add two tests to t4300 to illustrate these bugs.

21baa6e0c5 merge-tree: fix where two branches share no changes
15b4f7a (merge-tree: use ll_merge() not xdl_merge(), 2010-01-16)
introduced a regression to merge-tree to cause it to segfault when merging
files which existed in one branch, but not in the other or in the
merge-base. This was caused by referencing entry->path at a time when
entry was known to be possibly-NULL.

To correct the problem, we save the path of the entry we came in with,
as the path should be the same among all the stages no matter which
sides are involved in the merge.

f32e9852d4 add basic tests for merge-tree
merge-tree had no test cases, so here we add some very basic tests for
it, including some known-breakages.

[jc: with obvious/trivial fixups]
