Stop rerun when launch failed

[jmuheim]

I think that rerun should exit when it can't launch the app:

15:55:22 [rerun] Synaesthesia Launch Failed
15:55:23 [rerun] Watching . for {Gemfile.lock,config/environment.rb,config/environments/development.rb,config/initializers/*.rb,lib/**/*.rb} using Darwin adapter

Or do you expect the next time the launch will succeed?

I'd say we hope the next time it will succeed, yes :-)

I use rerun mostly for Ruby web apps; when the launch fails it's because of a syntax error and when I fix the error and save the file I want rerun to try again immediately.

If you want to run a command instead of a server, use the --exit (or -x) option.
