Fix handling of DNS names with '-' in them for sharenfs 

An old FreeBSD bugzilla report PR#168158 notes that DNS
names with '-'s in them cannot be used for the sharenfs
property.  This patch fixes the parsing of these DNS names.
The only negative affect this patch might have is that,
if a user has incorrectly separated options with a '-'
the sharenfs setting will no longer work once this patch
is applied.
