INN commit: trunk/innd (art.c)

[INN Commit]

    Date: Friday, October 23, 2009 @ 13:57:16
  Author: iulius
Revision: 8682

Fix a bug when articles were fed to innd via IHAVE or TAKETHIS
with an empty article:  the article terminator was not recognized.
Therefore, subsequent NNTP commands were eaten inside the article...

See also commit 8149 for the same issue with an empty body.
