Why have I done this?
- Because defaults.conf had a starting newline, which bugs me.
- Because moving the first line of FallBackConf looks unlovely.
- Because yaml happens to have a --- document-start syntax.
I completely agree that this is (hopefully) a no-op change;
but if anyone else thinks it makes things aesthetically more
pleasing, and agrees that it doesn't break anything, go ahead
and merge. ^_^
