Subject: [DOC] Moved `File.fnmatch?` to dir.rb

So that no longer disturbed by C comment delimiters.

+  # call-seq:
+  #    File.fnmatch( pattern, path, [flags] ) -> (true or false)
+  #    File.fnmatch?( pattern, path, [flags] ) -> (true or false)
+  #
+  # Returns true if +path+ matches against +pattern+.  The pattern is not a
+  # regular expression; instead it follows rules similar to shell filename
+  # globbing.  It may contain the following metacharacters:
+  #
+  # <code>*</code>::
+  #   Matches any file. Can be restricted by other values in the glob.
+  #   Equivalent to <code>/ .* /x</code> in regexp.
+  #
+  #   <code>*</code>::    Matches all files regular files
+  #   <code>c*</code>::   Matches all files beginning with <code>c</code>
+  #   <code>*c</code>::   Matches all files ending with <code>c</code>
+  #   <code>\*c*</code>:: Matches all files that have <code>c</code> in them
+  #                       (including at the beginning or end).
+  #
+  #   To match hidden files (that start with a <code>.</code> set the
+  #   File::FNM_DOTMATCH flag.
+  #
+  # <code>**</code>::
+  #   Matches directories recursively or files expansively.
+  #
+  # <code>?</code>::
+  #   Matches any one character. Equivalent to <code>/.{1}/</code> in regexp.
+  #
+  # <code>[set]</code>::
+  #   Matches any one character in +set+.  Behaves exactly like character sets
+  #   in Regexp, including set negation (<code>[^a-z]</code>).
+  #
+  # <code> \ </code>::
+  #   Escapes the next metacharacter.
+  #
+  # <code>{a,b}</code>::
+  #   Matches pattern a and pattern b if File::FNM_EXTGLOB flag is enabled.
+  #   Behaves like a Regexp union (<code>(?:a|b)</code>).
+  #
+  # +flags+ is a bitwise OR of the <code>FNM_XXX</code> constants. The same
+  # glob pattern and flags are used by Dir::glob.
+  #
+  # Examples:
+  #
+  #    File.fnmatch('cat',       'cat')        #=> true  # match entire string
+  #    File.fnmatch('cat',       'category')   #=> false # only match partial string
+  #
+  #    File.fnmatch('c{at,ub}s', 'cats')                    #=> false # { } isn't supported by default
+  #    File.fnmatch('c{at,ub}s', 'cats', File::FNM_EXTGLOB) #=> true  # { } is supported on FNM_EXTGLOB
+  #
+  #    File.fnmatch('c?t',     'cat')          #=> true  # '?' match only 1 character
+  #    File.fnmatch('c??t',    'cat')          #=> false # ditto
+  #    File.fnmatch('c*',      'cats')         #=> true  # '*' match 0 or more characters
+  #    File.fnmatch('c*t',     'c/a/b/t')      #=> true  # ditto
+  #    File.fnmatch('ca[a-z]', 'cat')          #=> true  # inclusive bracket expression
