users field in access groups in readers.conf

[John Newman]

Is there an artificially imposed 256 character limit?  When I
get a users: "user1,user2,user3.." entry with more than 256 
characters nnrpd craps out and denies access from anywhere and 
I get this in the log:

Jan 20 18:00:23 news.jump.net nnrpd[8607]: 206.196.95.10 syntax error in /News/l
ocal/etc/readers.conf(802), Expected value.
