Shell: more agressive shell pass-through experiment

[vindarel]

I want to mix shell and CL and see how it goes.

We have the Clesh syntax that provides the ! passthrough. It was also enabled in ciel-repl, but we can go further.

Now every command entered in the terminal REPL (or shell) that doesn't look like a lisp expression is considered a shell command, and run.

#+(or)
(progn
  (assert (lisp-command-p "(uiop:featurep"))
  (assert (lisp-command-p "uiop:*foo*"))
  (assert (lisp-command-p "*foo"))
  (assert (lisp-command-p "#foo"))
  (assert (lisp-command-p "-foo"))
  (assert (not (lisp-command-p "uiop featurep")))
  (assert (not (lisp-command-p "ls")))
  (assert (not (lisp-command-p "ls -l")))
  (assert (not (lisp-command-p "foo --arg=1:1"))))

next: for a good shell integration we need at least basic shell completion.

Lish is a fully functional Lisp shell that allows mixing shell commands and Lisp code. And it's much more featureful that our poor readline wrapper. So… use it?
