Subject: [PATCH] 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.
