Thanks, Rik, for the comment. You're right. Note that I've never been aware of such requirement because always in MKIV I use \head without \par.
@all, please comment it out this behaviour in somewhere. The weak point of context is documentation: wiki is too bit not updated and reference manual are outdated. As a simple user, it could cause nightmares, overall in transition to one major version to another.
