[Bug-readline] Stack overflow in vi mode when repeating dd

[Andreas Henriksson]

Hello,

Apologies if this bug has already been reported. :)

To reproduce the crash, in vi mode, type
<ESC>dd.

I discovered the problem in bash, and confirmed that it was a readline
problem with a minimal example. My readline version is 6.2.002 (as
distributed in Arch Linux, if it helps).

(gdb) bt -15

(the sequence repeats until the stack is full)
