What's the expression you guys use? "The pointy hat points at me."

It looks like I broke parsing of /etc/exports for the case where there
are continuation lines (I didn't have any of those in my test examples,
but do now;-).

Sorry about that. I'll be looking it over more carefully, but I'll bet
that the following patch fixes the problem (and I'm guessing you do have
contnuation lines in your /etc/exports?).

Please try this patch and see if it helps, rick
