When testing what happens on unmerged entries, the HEAD is the
commit we are starting from before the merge that fails and create
the unmerged entries. It is not the commit before.

Some previous patches added some tables to the "git reset"
documentation. These tables describe the behavior of "git reset"
depending on the option it is passed and the state of the files
in the working tree, the index, HEAD and the target commit.
This patch adds some tests to make sure that the tables describe
the behavior of "git reset".

Commit 9e8ecea (Add 'merge' mode to 'git reset', 2008-12-01) disallowed
"git reset --merge" when there was unmerged entries. But it wished if
unmerged entries were reset as if --hard (instead of --merge) has been
used. This makes sense because all "mergy" operations makes sure that
any path involved in the merge does not have local modifications before
starting, so resetting such a path away won't lose any information.
The previous commit changed the behavior of --merge to accept resetting
unmerged entries if they are reset to a different state than HEAD, but it
did not reset the changes in the work tree, leaving the conflict markers
in the resulting file in the work tree.
Fix it by doing three things:
- Update the documentation to match the wish of original "reset --merge"
better, namely, "An unmerged entry is a sign that the path didn't have
any local modification and can be safely resetted to whatever the new
HEAD records";
- Update read_index_unmerged(), which reads the index file into the cache
while dropping any higher-stage entries down to stage #0, not to copy
the object name from the higher stage entry. The code used to take the
object name from the a stage entry ("base" if you happened to have
stage #1, or "ours" if both sides added, etc.), which essentially meant
that you are getting random results depending on what the merge did.
The _only_ reason we want to keep a previously unmerged entry in the
index at stage #0 is so that we don't forget the fact that we have
corresponding file in the work tree in order to be able to remove it
when the tree we are resetting to does not have the path. In order to
differentiate such an entry from ordinary cache entry, the cache entry
added by read_index_unmerged() is marked as CE_CONFLICTED.
- Update merged_entry() and deleted_entry() so that they pay attention to
cache entries marked as CE_CONFLICTED. They are previously unmerged
entries, and the files in the work tree that correspond to them are
resetted away by oneway_merge() to the version from the tree we are
resetting to.

This patch makes "reset_index_file()" call "unpack_trees()" directly
instead of forking and execing "git read-tree". So the code is more
efficient.
And it's also easier to see which unpack_tree() options will be used,
as we don't need to follow "git read-tree"'s command line parsing
which is quite complex.
As Daniel Barkalow found, there is a difference between this new
version and the old one. The old version gives an error for
"git reset --merge" with unmerged entries, and the new version does
not when we reset the entries to some states that differ from HEAD.
Instead, it resets the index entry and succeeds, while leaving the
conflict markers in the corresponding file in the work tree (which
will be corrected by the next patch).
The code comes from the sequencer GSoC project:

Commit 9e8eceab ("Add 'merge' mode to 'git reset'", 2008-12-01),
added the --merge option to git reset, but there were no test cases
for it.
This was not a big problem because "git reset" was just forking and
execing "git read-tree", but this will change in a following patch.
So let's add a few test cases to make sure that there will be no
regression.

The old function was incorrect; in some instances it marks a cherry picked

Git 1.6.5.7
worktree: don't segfault with an absolute pathspec without a work tree
ignore unknown color configuration
help.autocorrect: do not run a command if the command given is junk
Illustrate "filter" attribute with an example
If a command is run with an absolute path as a pathspec inside a bare
repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen()
on NULL, which is the result of get_git_work_tree(), and segfaulted. It
should just fail instead.
Currently the function returns NULL even inside .git/ in a repository
with a work tree, but that is a separate issue.

When parsing the config file, if there is a value that is
syntactically correct but unused, we generally ignore it.
This lets non-core porcelains store arbitrary information in
the config file, and it means that configuration files can
be shared between new and old versions of git (the old
versions might simply ignore certain configuration).
The one exception to this is color configuration; if we
encounter a color.{diff,branch,status}.$slot variable, we
die if it is not one of the recognized slots (presumably as
a safety valve for user misconfiguration). This behavior
has existed since 801235c (diff --color: use
$GIT_DIR/config, 2006-06-24), but hasn't yet caused a
problem. No porcelain has wanted to store extra colors, and
we once a color area (like color.diff) has been introduced,
we've never changed the set of color slots.
However, that changed recently with the addition of
color.diff.func. Now a user with color.diff.func in their
config can no longer freely switch between v1.6.6 and older
versions; the old versions will complain about the existence
of the variable.
This patch loosens the check to match the rest of
git-config; unknown color slots are simply ignored. This
doesn't fix this particular problem, as the older version
(without this patch) is the problem, but it at least
prevents it from happening again in the future.

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.

The existing code checked to make sure we were not in a bare
repository when doing a hard reset. However, we should take
this one step further, and make sure we are in a worktree.
Otherwise, we can end up munging files inside of '.git'.
Furthermore, we should do the same check for --merge resets,
which have the same properties. Actually, a merge reset of
HEAD^ would already complain, since further down in the code
we want a worktree. However, it is nicer to check up-front;
then we are sure we cover all cases ("git reset --merge"
would run, even though it wasn't doing anything) and we can
give a more specific message.
Add tests to t7103 to cover these cases and some missing ones.

When loading a notes tree, the code primarily looks for SHA1-like paths
whose total length (discounting directory separators) are 40 chars
(interpreted as valid note entries) or less (interpreted as subtree
entries that may in turn contain note entries when unpacked).
However, there is an additional condition that must hold for valid
subtree entries: They must be _tree_ objects (duh).
This patch adds an appropriate test for this condition, thereby fixing
the crash that occured when passing a non-tree object to the tree-walk
API.
The patch also adds another selftest verifying correct behaviour of
non-notes in note trees.
