Patching or using a forked version of an Ansible Galaxy role

I maintain a lot of Ansible Galaxy roles. I probably have a problem, but I won't admit it, so I'll probably keep adding more roles :)

One thing I see quite often is someone submitting a simple Pull Request for one of my roles on GitHub, then checking in here and there asking if I have had a chance to merge it yet. I'm guessing people who end up doing this might not know about one of the best features of Ansible Galaxy (and more generally, open source!): you can fork the role and maintain your changes in the fork, and it's pretty easy to do.

I just had to do it for one project I'm working on. I am using the rvm_io.ruby role to install specific versions of Ruby on some servers. But there seems to have been a breaking change to the upstream packages RVM uses, summarized in this GitHub issue. I found a pretty simple fix (removing one array item from a variable), and submitted this PR.
