Since emacs 25.1
C-h f looking-back RET
shows:
looking-back is a compiled Lisp function in ‘subr.el’.
(looking-back REGEXP LIMIT &optional GREEDY)
...
This is because of
(declare
(advertised-calling-convention (regexp limit &optional greedy) "25.1"))
at the start of the looking-back implementation.
It still can be called with only one argument (in this cases LIMIT will
default to nil) and there are still a few such calls in the emacs core
lisp code.
This doesn't do any harm other than unnecessary
"[...]Warning: looking-back called with 1 argument, but requires 2-3"
noise in the compiling output while byte-compiling that files.
The patch below silence that (simply by explicitly adding nil as second
argument). This handles all such calls, that an el-search-load-path with
the pattern `(looking-back ,_) found (see
https://elpa.gnu.org/packages/el-search.html) with an appropriate
load-path. That means, if that works as promoted: this patch handles all
such cases curently still in the core.
