[PATCH] _rl_abort_internal: reset _rl_command_to_execute

[Grisha Levit]

If a key sequence ending with an isearch terminator is bound to a
function that longjmps, entering such a sequence during an isearch
causes readline to loop forever.

    echo '".\e": end-kbd-macro' > irc
    INPUTRC=irc bash --norc -in <<< $'X\n\cRX.\e'
