doc: fix mistake about matching against directories in "pattern.txt"

This fixes mistake of documentation about matching against directories
in "pattern.txt" introduced by 50db996bccaf.

".hgignore" treats specified "glob:" pattern as same as one specified
for "-X" option: it can match against directories, too.

For reference, extra regexp string appended to specified pattern for
each types are listed below: see also "match.match()" and
"match._regex()" for detail.

  ============= ========== ===============
  type          cmdline    -I/-X
  ============= ========== ===============
  glob/relglob  '$'        '(?:/|$)'
  path/relpath  '(?:/|$)'  '(?:/|$)'
  re/relre      (none)     (none)
  ============= ========== ===============

Appending '$' means that the specified pattern should match against
only files.

Mercurial accepts several notations for identifying one or more files
at a time.

By default, Mercurial treats filenames as shell-style extended glob
patterns.

Alternate pattern notations must be specified explicitly.

.. note::
  Patterns specified in ``.hgignore`` are not rooted.
  Please see :hg:`help hgignore` for details.

To use a plain path name without any pattern matching, start it with
``path:``. These path names must completely match starting at the
current repository root.

To use an extended glob, start a name with ``glob:``. Globs are rooted
at the current directory; a glob such as ``*.c`` will only match files
in the current directory ending with ``.c``.

The supported glob syntax extensions are ``**`` to match any string
across path separators and ``{a,b}`` to mean "a or b".

To use a Perl/Python regular expression, start a name with ``re:``.
Regexp pattern matching is anchored at the root of the repository.

To read name patterns from a file, use ``listfile:`` or ``listfile0:``.
The latter expects null delimited patterns while the former expects line
feeds. Each string read from the file is itself treated as a file
pattern.

All patterns, except for ``glob:`` specified in command line (not for
``-I`` or ``-X`` options), can match also against directories: files
under matched directories are treated as matched.

Plain examples::

  path:foo/bar   a name bar in a directory named foo in the root
                 of the repository
  path:path:name a file or directory named "path:name"

Glob examples::

  glob:*.c       any name ending in ".c" in the current directory
  *.c            any name ending in ".c" in the current directory
  **.c           any name ending in ".c" in any subdirectory of the
                 current directory including itself.
  foo/*.c        any name ending in ".c" in the directory foo
  foo/**.c       any name ending in ".c" in any subdirectory of foo
                 including itself.

Regexp examples::

  re:.*\.c$      any name ending in ".c", anywhere in the repository

File examples::

  listfile:list.txt  read list from list.txt with one file pattern per line
  listfile0:list.txt read list from list.txt with null byte delimiters
