INN 2.2: overview data gets truncated

[Sven Paulus]

Hi,

a very little bug in INN 2.2.x's nnrpd:

If you issue XOVER commands for the same article multiple times, each time
the overview line you get gets truncated by one character:

200 news.karlsruhe.org InterNetNews NNRP server INN 2.2.3 18-Jul-2000 ready (posting ok).

This fixes this behaviour (only happens with traditional spool and 
overviewmmap: false), maybe it should go to the 2.2 CVS branch for
