Oftentimes people will make the same change in two branches, revert the change
in one branch, and then be surprised when a merge reinstitutes that change when
the branches are merged. Add an explanatory paragraph that explains that this
occurs and the reason why, so people are not surprised.

Commit 07924d4 (diff: Introduce --diff-algorithm command line option
2013-01-16) added diff-algorithm as a parameter to the recursive merge
strategy but did not document it. Do so.

The (discouraged) -Xours/-Xtheirs modes of merge are supposed to
give a quick and dirty way to come up with a random mixture of
cleanly merged parts and punted conflict resolution to take contents
from one side in conflicting parts. These options however were only
passed down to the low level merge driver for text.
Teach the built-in binary merge driver to notice them as well.

The recursive merge strategy turns on rename detection but leaves the
rename threshold at the default. Add a strategy option to allow the user
to specify a rename threshold to use.

Add support for merging with ignoring line endings (specifically
--ignore-space-at-eol) when using recursive merging. This is
as a strategy-option, so that you can do:
git merge --strategy-option=ignore-space-at-eol <branch>
and
git rebase --strategy-option=ignore-space-at-eol <branch>
This can be useful for coping with line-ending damage (Xcode 3.1 has a
nasty habit of converting all CRLFs to LFs, and VC6 tends to just use
CRLFs for inserted lines).
The only option I need is ignore-space-at-eol, but while at it,
include the other xdiff whitespace options (ignore-space-change,
ignore-all-space), too.

Teach the merge-recursive strategy a --patience option to use the
"patience diff" algorithm, which tends to improve results when
cherry-picking a patch that reorders functions at the same time as
refactoring them.
To support this, struct merge_options and ll_merge_options gain an
xdl_opts member, so programs can use arbitrary xdiff flags (think
"XDF_IGNORE_WHITESPACE") in a git-aware merge.
git merge and git rebase can be passed the -Xpatience option to
use this.

Teach "git merge-recursive" a --renormalize option to enable the
merge.renormalize configuration. The --no-renormalize option can
be used to override it in the negative.
So in the future, you might be able to, e.g.:
git checkout -m -Xrenormalize otherbranch
or
git revert -Xrenormalize otherpatch
or
git pull --rebase -Xrenormalize
The bad part: merge.renormalize is still not honored for most
commands. And it reveals lots of places that -X has not been plumbed
in (so we get "git merge -Xrenormalize" but not much else).

Make it clear in the docs that the merge takes the tree of HEAD and
ignores everything in the other branches. This should hopefully clear
up confusion, usually caused by the user looking for a strategy that
resolves all conflict hunks in favour of HEAD (which is completely
different and currently not supported).

There was already some documentation about subtree under
Documentation/howto but it was missing from git-merge manpage.
