description:
When we initialize libedit (editline) always call ourselves "sh" no
matter what $0 is (or is not) set to.   This means that editrc(5)
lines that start "sh:" are used (in addition to those with no prefix,
which will usually be most of them), regardless of the name or manner in
which we were invoked.
