Hi,

sounds stupid, but I grepped build log of current -current for phrase "no such"

One piece:

#    format  man8/trace.cat8
PATH=/var/worksrc/netbsd-current/tools/lib/groff:${PATH} /var/worksrc/netbsd-current/tools/bin/nbnro
ff -mandoc /volatile/worksrc/netbsd-current/src/gnu/dist/postfix/man/man8/trace.8   > trace.cat8.tmp
 && mv trace.cat8.tmp trace.cat8
 /volatile/worksrc/netbsd-current/src/gnu/dist/postfix/man/man8/trace.8:3: can't open `man8/bounce.8' : No such file or directory

And really -- in my system there is just empty trace(8) manpage.  AFAIU it should
be a link to the bounce manpage.

Maybe it is just nice thing to have -- if, for example, autobuild system would check
build logs for some catchy words.
