* 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.
