`..-}' does not terminate comment

[vvv]

Sequence of '..-}' within a comment breaks syntax highlighting: code that follows will be displayed in font-lock-comment-face. Highlighting works correctly is there is a space between dots and '-}'.

Example:

module Test where

{- Dot, dot, space.. -}
test1 = undefined

{- Just dot, dot..-}
test2 = undefined

Compare with c-mode:

/* Dot, dot, space.. */
test1();

/* Just dot, dot..*/
test2();

Question mark instead of dot has the same effect. I suspect the bug to be exposable by any punctuation character.

In fact, it was due to a difference in syntax inside and outside comments. Fixed by conditionalizing on that.
