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.
