More Lisp

I continue to gain confidence with (Emacs) Lisp. I used to have a hacked up (my-find) function that worked reasonably well but was a bit flaky and capable of missing stuff in other languages. It turns out it's faster to ask git a lot of these questions if your working in a source controlled environment. A quick hack later and f5 magically does that if it sees a .git directory when I start up. I feel I can justify mentioning the language on my CV :-)
