[TxMt] Objective-C comments scope missing?

Hi everyone,

I've recently started coding in Objective-C and noticed that none of the comments in my ".m" source files are syntax colored. CNTL-SHIFT-P shows the comments' scope as:

source.objc meta.implementation.objc meta.scope.implementation.objc

Essentially, the same scope as the rest of the code. For comments, I would have expected to also see something like:

comment-line-double-slash.objc

And also:

comment-block.objc

Any ideas how I can remedy this? BTW, I'm using TextMate v1.5.7 (build 1455). Have I somehow unwittingly screwed up my Objective-C TM bundle?

Thanks,
