The patch below adds the yacc documentation obtained from 4.3BSD-Reno via TUHS's archives. There are some incompatibilities between the -msU macros that this documentation was written in and the -ms macros, but I am not a troff person so I haven't attempted to fix it. There are of course lots of other sections of the documentation that are missing because they have in the past been encumbered. I can prepare patches for adding them as well, if you want.
