Rewrite chruby-exec as a function

[postmodern]

If chruby-exec were a function, it would always run in the current shell. It could also reuse other chruby functions.

Pseudo Code

function chruby_exec()
{
  (chruby $arguments && eval $command)
}

If chruby-exec is a function, won't it no longer be usable as a way to use chruby-based installs via cron?

[postmodern]

Correct. It would force users to explicitly invoke chruby-exec within a shell. This would be one way to prevent users from invoking chruby-exec under the dash shell. Of course, maybe people should just go back to bash -l -c "chruby ...; command here".
