bug of xhdr

[Damien Masse]

I found this bug in INN version 2.2 (and version 2.1) :
when you ask for the last header of the overview file with the 'xhdr'
command, nnrp displays each header followed by a "\n<number> ".
Either because the function OVERGetHeader in nnrpd/article.c should
test the end of line (and doesn't do it), or because the function
OVERfind should put a '\0' at the end of the line it returns.

Hope this was not already fixed.
