Opening paren matches with closing paren in character literal

As of version 0.3.0, I get the following:

Same problem with back-ticks:

The only thing I've found is that a string literal ")" has got a special token type String and doesn't suffer from the issue.

I suggest that we add a low priority scope string.quoted.other to the character literal, which will be shadowed by it's "proper scope" constant.character.literal.scala. This will mark token as String and apparently helps the issue:

As for the backticks I think we should leave them as they are, as rules for them are scattered all over the code, and some vars in backticks shouldn't have any scope at all which prevents the use of above hack.

This sounds like a reasonable approach. I suspect ')' are much more common than backticked identifiers with parentheses.
