colours of comments work for some, but not all common languages.

Hi, good job with this plugin! From initial testing of v0.2.9.21, it seems like the colours are coming through OK, however, the colours of comments still seem patchy. In 64-bit Notepadd++, using the context menu "plugin commands -> copy text with syntax highlighting"

In C or C#, comments made with // and /// come through with colour, but comments made with /* */ come through as black&white. In Python, comments made with # come though as black&white. In R, comments made with # come through with colour. In Haskell, comments made with -- come through with colour. (I have not tried any other languages)

I hope this would be a simple fix. If so, I would really appreciate the update. Many Thanks.
