/etc/exports is now being read incorrectly

[Geoff Wing]

Hi,
for a long time, the parser reading /etc/exports would treat the following
example from exports(5):

        /u -maproot=bin: -network 131.104.48 -mask 255.255.255.0

as 131.104.48/24

Currently it's being treated as 131.104.0.48 (seen via ``showmount -e'')

I'm guessing it changed in the last month or so.

Regards,
Geoff
