  59 Called interactively pastebin uses the current region for
  60 preference for sending... if the mark is NOT set then the entire
  61 buffer is sent.
  62
  63 Argument START is the start of region.
  64 Argument END is the end of region.
  65
  66 If PREFIX is used pastebin prompts for a prefix to be used as the
  67 virtual host to use.  For example use 'emacs' for 'emacs.pastebin.com'."
