Section B says:

It should say:

Some comment lines in the example termcap file appear to have improperly reformatted to fit the 78-character limit; the needed "# " was ommitted.

Section Appendix A says:

   The two characters "%s", if used, will be replaced by the name of a
   file for the actual mail body data.  In the case of the edit adn
   view-command, the body part will be passed to this command as
   standard input unless one or more instances of "%s" appear in the
   view-command, in which case %s will be replaced by the name of a file
   containing the body part, a file which may have to be created before
   the view-command program is executed.

It should say:
