Re: `looking-back' strange warning

It's not a bug. It's declared as demanding two arguments so that people
will use it.
M-x `byte-compile-file' warns:

... Warning: looking-back called with 1 argument, but
    requires 2-3


While its definition:

(defun looking-back (regexp &optional limit greedy)


Docu bug?

Cheers,

Andreas
