If a keymap shadows a function or macro binding, the dumping code will
print this as `\000', which is not correct if the output is reused as
input.
$ bind '"\e": "X"'; bind -s
"\e\000": "X"
$ bind -u undo; bind '"\e": undo'; bind -p | grep ': undo'
"\e\000": undo
Change _rl_get_keyname to represent this as a zero-length string.
