It seems that there should be some, at least minimal, ability to wrap long lines in block comments to the page width.
I believe that the AutoFormat plugin is supposed to do this, however it is broken with the EAP builds and this seems like something that is really fundamental and perhaps should be part of the core.

Obviously these are not identical to javadoc comment text, mostly noting the absence of HTML directives. But otherwise the same formatting would apply – just take blank lines to mean blank lines, not new "<p>" directives. Just preserve my comment leader and that's fine.
I would think that if this is done, also formatting blocks (or selected sets of) standalone block comments would be easy to include. It's just a different comment leader at some level. Lots of folks use successive lines of "//" comments instead of "/.../" comments.
