Comment #4 on issue 2646 by [email protected]: Parenthesizing multi measure rests

Patchy is an automatic script that checks that patches don't break the build. The odd filename is a feature of temporary files created during a build. With a full doc build, the logfiles are saved and so the source of the error can be analysed. This doesn't appear to happen with patchy. The solution is to start with clean master, apply your patch and make, make doc, make test. If you can't do that, let me know and I'll do it for you.
