(c-indent-new-comment-line): Added a kludge

(c-indent-new-comment-line): Added a kludge
similar to the one in c-fill-paragraph to check the fill
prefix from the adaptive fill function for sanity.
(c-electric-brace): Fixed some bugs in the state
handling that caused class open lines to be recognized as
statement-conts in some cases.
(c-indent-new-comment-line): Keep the fill prefix
guessed by the adaptive fill function unless point is on the
first line of a block comment.
(c-indent-command): Obey c-syntactic-indentation.
(c-electric-brace, c-electric-slash,
c-electric-star, c-electric-semi&comma, c-electric-colon,
c-electric-lt-gt, c-electric-paren): Don't reindent old lines
when c-syntactic-indentation is nil.
(c-fill-paragraph): Keep one or two spaces
between the text and the block comment ender when it hangs,
depending on how many there are before the fill.
(c-indent-new-comment-line): Always break
multiline comments in multiline mode, regardless of
comment-multi-line.
