The filling and indentation code in latex.el tries hard to support outer
and inner indentation of commented passages of text.  It seems the
handling of fill prefixes broke when I implemented this feature.

You can get some better results by activating Adaptive Fill mode and
adding "+" to `adaptive-fill-regexp'.  The problem remaining with this
approach is an excessive blank after the fill prefix which is not taken
care of by the indentation code.
