While current implementation of ngxBlock looks incorrect, I don't 
see how it breaks highlighting of the rewrite in question.  Could 
you please elaborate?

On the other hand, the rewrite highlighting is clearly incorrect 
either. Rewrite arguments (much like any other directive 
arguments) can be escaped strings, and the rewrite parsing as 
implemented in the patch 2 doesn't take it into account, hence it 
will be broken with a configuration like:

    rewrite "/foo bar/" /bazz/ last;

In general, it might be better idea to start with general 
configuration syntax matching instead of focusing on the ad-hoc 
solutions for some particular directives.  And removing ngxBlock 
looks like a step in the wrong direction to me, as it is a basic 
concept of the configuration syntax.
