Misc tweaks

Hi Karen!

This is today's pull request for the 24pullrequests challenge. You're probably thinking "huh?", so I'll explain how it came about :-)

I prep each PR the night before and push my changes to github ready. But I woke up this morning to discover that the intended recipient had noticed my changes and merged them, so I was PR-less for today.

I decided to trial-run my plan for the 2015 PR challenge, and picked a dist at random. I got this one :-)
