A new version of less has been released for beta testing. This version changes the behavior of the new -A option which was introduced in less-440. The meaning of the -A option is basically the opposite of what it was in less-440: the new search behavior is now the default, and -A invokes the old (pre-440) search behavior.
This version is being announced now as a beta but it is expected to become the new release version within a week or two. You can download the source for less-441 from http://www.greenwoodsoftware.com/less/download.html --Mark
