What is the meaning of the "swallow" key for language rules? I searched the archives, wiki and documentation but I couldn't find a good definition. Did I miss something?

It’s deprecated. But it is shorthand for having one sub-rule, e.g.:

{ begin = '"'; end = '"'; swallow = '\.'; }

Is the same as:

{ begin = '"'; end = '"'; patterns = ( { match = '\.'; } ); }
