Hi, this PR includes only fix to typos, grammar improvements for the quickfix package documentation, and code generation.
The code generation was necessary because one of the typos was in _gen/generate-messages/main.go.
I've added all the info in the commit messages.
I've ran all the tests, including make accept, all tests passed.
I hope this is helpful to the project. I'm really impressed with it and would love to join you in contributing.
