:(glob)path differs from plain pathspec that it uses wildmatch with
WM_PATHNAME while the other uses fnmatch without FNM_PATHNAME. The
difference lies in how '*' (and '**') is processed.
With the introduction of :(glob) and :(literal) and their global
options --[no]glob-pathspecs, the user can:
- make everything literal by default via --noglob-pathspecs
--literal-pathspecs cannot be used for this purpose as it
disables _all_ pathspec magic.
- individually turn on globbing with :(glob)
- make everything globbing by default via --glob-pathspecs
- individually turn off globbing with :(literal)
The implication behind this is, there is no way to gain the default
matching behavior (i.e. fnmatch without FNM_PATHNAME). You either get
new globbing or literal. The old fnmatch behavior is considered
deprecated and discouraged to use.

--literal-pathspecs and its equivalent environment variable are
probably used for scripting. In that setting, pathspec magic may be
unwanted. Disabling globbing in individual pathspec can be done via
:(literal) magic.

The prefix length is passed from one command to another via the new
magic 'prefix'. The magic is for parse_pathspec's internal use only,
not visible to parse_pathspec's callers.
Prefix length is not preserved across commands when --literal-pathspecs
is specified (no magic is allowed, including 'prefix'). That's OK
because we know all paths are literal. No magic, no special treatment
regarding prefix. (This may be no longer true if we make :(glob)
default)
Other options to preserve the prefix include saving it to env variable
or quoting. Env var way (at least _one_ env var) is not suitable
because the prefix is not the same for all pathspecs. Pathspecs
starting with "../" will eat into the prefix part.
We could also preserve 'prefix' across commands by quoting the prefix
part, then dequoting on receiving. But it may not be 100% accurate, we
may dequote longer than the original prefix part, for example. That
may be good or not, but it's not the purpose.

Prepending prefix to pathspec is a trick to workaround the fact that
commands can be executed in a subdirectory, but all git commands run
at worktree's root. The prefix part should always be treated as
literal string. Make it so.

This patch is essentially no-op. It helps catching new use of this
field though. This field is introduced as an intermediate step for the
pathspec conversion and will be removed eventually. At this stage no
more access sites should be introduced.

match_pathspec_depth was created to replace match_pathspec (see
61cf282 (pathspec: add match_pathspec_depth() - 2010-12-15). It took
more than two years, but the replacement finally happens :-)

This passes the pathspec, more or less unmodified, to
git-add--interactive. The command itself does not process pathspec. It
simply passes the pathspec to other builtin commands. So if all those
commands support pathspec, we're good.

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
converted to use parse_pathspec.

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.

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.

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.
