nil when calling fill-paragraph, to avoid bogus recursion which
will signal an error.
(c-fill-paragraph): Always keep point in the same
relative position. Fill comment before point if there's nothing
else on the same line. Fill block comments after code a little
better. Try harder to find a good fill-prefix when point is on a
block comment ender line. Use c-Java-javadoc-paragraph-start in
block comments in Java mode. Leave block comment ender alone when
c-hanging-comment-ender-p is nil and point is on that line.
Detect paragraph-separate in multiparagraph comments. Fix for bug
that may strip the `*' off `*/' if fill-prefix ends with `*' and
c-hanging-comment-ender-p is t. Added filling of multiline string
literals. Always return t to disable filling in any unhandled
area, i.e. actual code where fill-paragraph only mess things up.
