OK, so in JOE 2.9.7pre2 are still bugs concerning wordwrap and delete of last character in the line when reformatting. If anyone is able to write any type of patch for wordwrapping (there is no need to be clean, documented, ..) please mail it to me. I'm without computer and will be until I found room to live, so right now my problems are somewhere else. This version was only released by me, but was developed by vsamel. On the other side is true that I should test it more :(
So again any form of patch will be accepted for this problem.
