INN commit: trunk/innd (art.c)

[INN Commit]

    Date: Saturday, October 25, 2008 @ 16:26:12
  Author: iulius
Revision: 8149

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

Thanks to Wolfgang M. Weyand for having reported this issue.
