/etc/zfs/exports conversion problem

[Tim Rice]

Whatever program creates /etc/zfs/exports from a "zfs set sharenfs ...." 
command
does not act correctly if hostnames have a - in them.

I first spotted this on a 10.3 system.
Still exists in 11 RC2

Steps to reproduce.
On the 11.0-RC2 EC2 instance I spun up, the pool name was tstpool

# zfs create tstpool/some-test-fs
# zfs set \
sharenfs='rw=devlab16-79.newjersey.sco.com,root=devlab16-79.newjersey.sco.com' 
\
tstpool/some-test-fs
# cat /etc/zfs/exports
# !!! DO NOT EDIT THIS FILE MANUALLY !!!

/tstpool/some-test-fs    rw=devlab16 79.newjersey.sco.com root=devlab16 
79.newjersey.sco.com
# zfs get sharenfs tstpool/some-test-fs
NAME                  PROPERTY VALUE SOURCE
tstpool/some-test-fs  sharenfs 
rw=devlab16-79.newjersey.sco.com,root=devlab16-79.newjersey.sco.com local


Note the missing dash between 16 and 79 in /etc/zfs/exports but the 
sharenfs property
is correct.

Sorry I haven't had time to track down where the trouble is. I just ran 
into this
setting up a storage server.
