But remember that this also effects command line expansion inside
shell scripts.  There are plenty of times you want dollar-sign
expansion inside a shell script but don't want what is essentially a
lame keyboard editing interface.  (If one wants a previous command in
bash one can use Ctrl-R, or Ctrl-P which is quite a bit more WYSIWYG.)
