Minor 'help' defect.

[thutt]

I'd like to report the minor issue that the 'help builtin' command has
an extra '.' at the end of the 'exit status' section.

  bash --version
  GNU bash, version 4.2.25(1)-release (x86_64-pc-linux-gnu)

  builtin: builtin [shell-builtin [arg ...]]
      Execute shell builtins.

      Execute SHELL-BUILTIN with arguments ARGs without performing command
      lookup.  This is useful when you wish to reimplement a shell builtin
      as a shell function, but need to execute the builtin within the function.

      Exit Status:
      Returns the exit status of SHELL-BUILTIN, or false if SHELL-BUILTIN is
      not a shell builtin..
