When adding an overview line with OVadd(), check that Xref: is
at the beginning of an overview field (that is to say that a
tabulation precedes it).

Otherwise, if for instance one has User-Agent:full in LIST
OVERVIEW.FMT and an article is received with the following
header field:
User-Agent: test Xref: server test:50
then the overview data for article 50 in newsgroup test is
replaced by the one of this article.  And the real article
number of this article is unknown for the overview.

END
