* debug.c (last_command): Initialize to empty string rather

than nil, otherwise hitting enter tries to repeat the nil command.
(show_bindings): New function. Prints all levels of bindings.
(debug): Flip the corresponding print flags after printing the current
form or data, so they are not printed for every prompt.
On EOF from standard input, substitute the q command.
If enter is hit and there is no last command, just re-print the prompt.
The v command uses show_bindings to dump the environment.

* eval.c (eval): When calling debug_check, pass the env objects, rather
than the bindings it contains.
