Binding to `exit` command causes `TypeError`

inputrc:

Control-d: exit

❱ ./bin/console
irb(main):001> ^D
RELINE_SRCDIR/lib/reline/line_editor.rb:975:in 'Kernel#exit': no implicit conversion of String into Integer (TypeError)

I didn't follow the whole call chain, but I'm guessing key.method_symbol == :exit and wrap_method_call simply grabs the method from top-level Kernel and calls it with a string parameter, causing the TypeError exception.

Inspect lib/reline/line_editor.rb around wrap_method_call and the referenced method lookup and call sites. Reproduce the inputrc binding with Control-d and verify that binding it to exit no longer raises TypeError and performs the expected command behavior.
