Unrecognized pragmas in declaration position make the layout wacky

[nibro]

This fails to parse:

{-# OPTIONS #-}
{-# LINE 49 "src/Language/C/Parser/Lexer.x" #-}
module Fail where

The reason is that the lexer doesn't emit a virtual semi-colon after the unrecognized LINE pragma closes. I currently don't know how to fix this.

All unrecognised pragmas are now handled by the comment lexing code (as opposed to discarded as comments by the pragma lexing code). This means layout won't be a problem. The above example now works, case closed.
