Motivation

I'm using astring as part of an atom plugin to help with code generation. It would be great to be able to control whether semicolons are emitted, so that I can match the current style directives of the current project. Right now, semicolons are implemented as a whole bunch of state.write(';') instances.

It would be awesome to have a config option to control semicolon emission. I'm thinking that you could replace all those writes with a semantic state.terminate(), which can check if it should print a semicolon or not.

The only alternative to control this is to basically fork the entire baseGenerator, so you can remove all those writes.
