File Name Patterns

    Mercurial accepts several notations for identifying one or more files
    at a time.
    By default, Mercurial treats filenames as shell-style extended glob
    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
    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
