The BRL (now part of ARL) Bourne shell already had those, also a $HISTORY file (called $HISTFILE to avoid conflict), emacs-style command line editing, etc. In fact I'm still using it; we have a single source that can be conditionally configured to fit any known Unix platform, which vary a lot more than one might think. It also supports csh-like job control, and as a side effect uncovered a very bad, pervasive race in the Irix kernel (which was soon fixed).
