Quick fix to handle commented blocks in sublexer

@weaverryan @WebMamba it may need a second look as i find weird the changes made do not have any other impacts...

Hum, I think if we have a problem with comments we also have an issue with the verbatim tag? And I think an easier solution could be if the pointer consumes {# then moves the pointer position to the next #} as we do at the top. With this method, you can remove all your condition

I just wanted to fix the specific issue there.. and i guess a lot more people uses block in comments (in a dev phase it is a frequent thing) than verbatim :)

But it's an issue indeed.

I do believe we can fix and improve some things here... but i'd suggest to do it a bit differently and that seems to me another (bigger) discussion.

WDYT ?
We can open an issue if you want to discuss this next move ?

Sadly not if we want to handle properly verbatim + comments + strings + ....

This moves things a small step forward - thanks Simon!
