Not really no. And it would make ragel a build dependency.

That's fine, it just makes unicorn a bit harder to use outside of
rubygems releases. But long story short bundler git gems is
pretty much:

  - git clone repo
  - gem build repo.gemspec
  - gem install repo-...

So nothing is executed besides the extconf.rb. Which mean
the version file and the generated.c file would need to be
committed in the repository rather than in .gitignore.

But really I don't think so many people need to use unicorn
branches.

I'd say not even. It's just for people like me trying to run branches.
