>Description:
Yesterday, while bug watching, we spotted a bug couple so rare that it
was thought to be extinct for over 24 years.  Even more lucky, we were
able to spot where it nests in mere seconds.

showmount(1) neglects to separate the exported directory from the list
of exported-to groups IFF the path is exactly 35 characters:

$ showmount -e fec0::2
Exports list on host:
/Users/bad/netbsd-gsoc/src-tutorial/obj ::1 127.1
/Users/bad/netbsd-gsoc/src-tutorial::1 127.1
/Users/bad/work/emacs-git/emacs-src192.168.56.4
$ 

Pullups all the way down to 1.6.

>How-To-Repeat:
Export some directories whose absolute path is exactly 35 characters.

>Fix:
Yes please.
