* Applied wesley.craig@umich.edu's KPOP patches. According to him:

      The following patch fixes a problem with requesting a service key for a
      machine that has multiple 'A' records.  It also makes "-kpop" a command
      line option, for users who would like to use both "kpop" and "pop".

  Did no testing of the new features, as I don't have access to a KPOP server.

  One tweak I made to the patch he sent to nmh-workers was to move the
  declaration of his new hp2 variable into the #ifdef KPOP section so you don't
  get an "unused variable" warning when compiling without KPOP.

* Modified inc.man and msgchk.man to document Wesley's new -kpop.
