Ruby optparser bash completion support

Hi all, For ages, there is Bash/Zsh completion support available for the default OptParser [1]. That means quite some Ruby application could provide some basic command completion out of the box. However, the setup is a bit clumsy. The steps necessary to enable the command completion for single executable are described her [2]. Any ideas, how we could benefit from this feature? Should we store the "rb_optparse.bash" somewhere? Where to load it and how to enable the completion for specific executables? Should we try to enable the bash completion for every Ruby executable? Should we have some macro for this? Vít [1] https://github.com/ruby/ruby/commit/644f0445e86034dde399d6db8261c82cf34b8e07 [2] https://github.com/ruby/ruby/blob/trunk/misc/rb_optparse.bash
