check-ignore (at least the test suite) seems to rely on the pattern
order. PATHSPEC_KEEP_ORDER is introduced to explictly express this.
The lack of PATHSPEC_MAXDEPTH_VALID is sufficient because it's the
only flag that reorders pathspecs, but it's less obvious that way.

GUARD_PATHSPEC() marks pathspec-sensitive code, basically all those
that touch anything in 'struct pathspec' except fields "nr" and
"original". GUARD_PATHSPEC() is not supposed to fail. It's mainly to
help the designers catch unsupported codepaths.

This makes 'original' suitable for passing to an external command
because all pathspec magic is left in place, provided that the
external command understands pathspec. The prefixing is needed because
we usually launch a subcommand at worktree's top directory and the
subcommand can no longer calculate the prefix itself.
This slightly affects the original purpose of 'original'
(i.e. reporting). We should report without prefixing. So only turn
this flag on when you know you are about to pass the result straight
away to an external command.

PATHSPEC_SYMLINK_LEADING_PATH and _STRIP_SUBMODULE_SLASH_EXPENSIVE are
respectively the alternate implementation of
pathspec.c:die_if_path_beyond_symlink() and
pathspec.c:check_path_for_gitlink(). They are intended to replace
those functions when builtin/add.c and builtin/check-ignore.c are

match_pathspec_depth() and tree_entry_interesting() check max_depth
field in order to support "git grep --max-depth". The feature
activation is tied to "recursive" field, which led to some unwanted
activation, e.g. 5c8eeb8 (diff-index: enable recursive pathspec
matching in unpack_trees - 2012-01-15).
This patch decouples the activation from "recursive" field, puts it in
"magic" field instead. This makes sure that only "git grep" can
activate this feature. And because parse_pathspec knows when the
feature is not used, it does not need to sort pathspec (required for
max_depth to work correctly). A small win for non-grep cases.
Even though a new magic flag is introduced, no magic syntax is. The
magic can be only enabled by parse_pathspec() caller. We might someday
want to support ":(maxdepth:10)src." It all depends on actual use
cases.
max_depth feature cannot be enabled via init_pathspec() anymore. But
that's ok because init_pathspec() is on its way to /dev/null.

These call sites follow the pattern:
paths = get_pathspec(prefix, argv);
init_pathspec(&pathspec, paths);
which can be converted into a single parse_pathspec() call.

We have two ways of dealing with empty pathspec:
1. limit it to current prefix
2. match the entire working directory
Some commands go with #1, some #2. get_pathspec() and parse_pathspec()
only support #1. Make parse_pathspec() reject empty pathspec by
default. #1 and #2 can be specified via new flags. This makes it more
expressive about default behavior at command level.

We usually use pathspec_item's match field for pathspec error
reporting. However "match" (or "raw") does not show the magic part,
which will play more important role later on. Preserve exact user
input for reporting.

Currently to fill a struct pathspec, we do:
const char **paths;
paths = get_pathspec(prefix, argv);
...
init_pathspec(&pathspec, paths);
"paths" can only carry bare strings, which loses information from
command line arguments such as pathspec magic or the prefix part's
length for each argument.
parse_pathspec() is introduced to combine the two calls into one. The
plan is gradually replace all get_pathspec() and init_pathspec() with
parse_pathspec(). get_pathspec() now becomes a thin wrapper of
parse_pathspec().
parse_pathspec() allows the caller to reject the pathspec magics that
it does not support. When a new pathspec magic is introduced, we can
enable it per command after making sure that all underlying code has no
problem with the new magic.
"flags" parameter is currently unused. But it would allow callers to
pass certain instructions to parse_pathspec, for example forcing
literal pathspec when no magic is used.
With the introduction of parse_pathspec, there are now two functions
that can initialize struct pathspec: init_pathspec and
parse_pathspec. Any semantic changes in struct pathspec must be
reflected in both functions. init_pathspec() will be phased out in
favor of parse_pathspec().

Because free_pathspec wants to free "items" pointer in the pathspec
structure, a simple structure assignment is not enough if you want to
copy an existing pathspec into another. Freeing the original will
damage the copy unless a deep copy is made.
Note that the strings in pathspec->items->match and the array
pathspec->raw[] are still shared between the original and the copy.

The document says one cannot push from a shallow clone. But that is
not true (maybe it was at some point in the past). The client does not
stop such a push nor does it give any indication to the receiver that
this is a shallow push. If the receiver accepts it, it's in.
Since 52fed6e (receive-pack: check connectivity before concluding "git
push" - 2011-09-02), receive-pack is prepared to deal with broken
push, a shallow push can't cause any corruption. Update the document
to reflect that.

"git stash save" is not just about "saving" the local changes, but
also is to restore the working tree state to that of HEAD. If you
changed a non-directory into a directory in the local change, you
may have untracked files in that directory, which have to be killed
while doing so, unless you run it with --include-untracked. Teach
the command to detect and error out before spreading the damage.

Earlier remote.pushdefault (and per-branch branch.*.pushremote)
were introduced as an additional mechanism to choose what
repository to push into when "git push" did not say it from the
command line, to help people who push to a repository that is
different from where they fetch from. This attempts to finish that
topic by teaching the default mechanism to choose branch in the
remote repository to be updated by such a push.
The 'current', 'matching' and 'nothing' modes (specified by the
push.default configuration variable) extend to such a "triangular"
workflow naturally, but 'upstream' and 'simple' have to be updated.
. 'upstream' is about pushing back to update the branch in the
remote repository that the current branch fetches from and
integrates with, it errors out in a triangular workflow.
. 'simple' is meant to help new people by avoiding mistakes, and
will be the safe default in Git 2.0.
In a non-triangular workflow, it will continue to act as a cross
between 'upstream' and 'current' in that it pushes to the current
branch's @{upstream} only when it is set to the same name as the
current branch (e.g. your 'master' forks from the 'master' from
the central repository).
In a triangular workflow, this series tentatively defines it as
the same as 'current', but we may have to tighten it to avoid
surprises in some way.
