I guess I need this in my personal tree:

diff --git a/Michael b/Michael
index 5318944..2ff6a75 100644
--- a/Michael
+++ b/Michael
@@ -0815,2 +0815,2 @@ endif

-stupid remark about lower case
-stupid question about escaping $
+compensate for lack of morning coffee
+note that an empty shell var is more than nothing at all
