:(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.

Windows disallows file names that contain a star. Arrange the test setup
to insert the file name "f*" in the repository without the corresponding
file in the worktree.

Git takes pathspec arguments in many places to limit the
scope of an operation. These pathspecs are treated not as
literal paths, but as glob patterns that can be fed to
fnmatch. When a user is giving a specific pattern, this is a
nice feature.
However, when programatically providing pathspecs, it can be
a nuisance. For example, to find the latest revision which
modified "$foo", one can use "git rev-list -- $foo". But if
"$foo" contains glob characters (e.g., "f*"), it will
erroneously match more entries than desired. The caller
needs to quote the characters in $foo, and even then, the
results may not be exactly the same as with a literal
pathspec. For instance, the depth checks in
match_pathspec_depth do not kick in if we match via fnmatch.
This patch introduces a global command-line option (i.e.,
one for "git" itself, not for specific commands) to turn
this behavior off. It also has a matching environment
variable, which can make it easier if you are a script or
porcelain interface that is going to issue many such
commands.
This option cannot turn off globbing for particular
pathspecs. That could eventually be done with a ":(noglob)"
magic pathspec prefix. However, that level of granularity is
more cumbersome to use for many cases, and doing ":(noglob)"
right would mean converting the whole codebase to use
"struct pathspec", as the usual "const char **pathspec"
cannot represent extra per-item flags.
