relatedly! RFH: make C-d in debugger not terminate process

[Andy Wingo]

Hello!

I am currently poking about to make it possible to run a recursive repl,
from the debugger, in the context of the error. It would be nice to be
able to exit said recursive repl via Control-D, and it would likewise be
nice to be able to exit the debugger via Control-D. I'm sure this is
possible. Can someone hook this up?

Thanks!

What about C-] as in Emacs?

Ah yes that would be nice as well. Both would be nice, in fact ;)

By the way we do have a recursive repl from the debugger now, but you
have to exit it with (quit). For example:

  scheme@(guile-user)> (let ((a 10) (b 0)) (/ a b))
  Throw to key `numerical-overflow':
  ERROR: In procedure /:
  ERROR: Numerical overflow
  Entering the debugger. Type `bt' for a backtrace or `c' to continue.
  0 debug> bt 2
  In module/ice-9/boot-9.scm:
     61:  1 (call-with-prompt prompt0 #<procedure 8fe40e0 at modu...> #)
  In current input:
      1:  0 (#<procedure 8fe40f0 at <current input>:1:0 ()>)
  0 debug> repl
  Read-only local variable a = 10
  Read-only local variable b = 0
  scheme@(#{\ g35}#) [1]> a
  $1 = 10
  scheme@(#{\ g35}#) [1]> (quit)
  0 debug> bt
  In module/ice-9/boot-9.scm:
   1056:  2 (#<procedure 8f33060 ()>)
     61:  1 (call-with-prompt prompt0 #<procedure 8fe40e0 at modu...> #)
  In current input:
      1:  0 (#<procedure 8fe40f0 at <current input>:1:0 ()>)
  0 debug> up
  #1  0x00000016 in (call-with-prompt prompt0 #<procedure 8fe40e0 at mo...> #)
  1 debug> repl
  Read-only local variable tag = prompt0
  Read-only local variable thunk = #<procedure 8fe40e0 at module/sys...>
  Read-only local variable handler = #<procedure default-prompt-hand...>
  scheme@(#{\ g76}#) [1]> handler
  $2 = #<procedure default-prompt-handler (k proc)>

Et cetera...
