Hi,

Local variable name completion in ELisp seems to fail at uneven setq
argument positions:

1. emacs -Q
2. Permit local variables analysis in scratch buffer by evaluating
   (setq-local trusted-content :all)
3. Insert:
   (defun foo (barbaz) bar)
4. Place point after "bar" and hit C-M-i
5. See "bar" completed to "barbaz", as expected
6. Now insert instead:
   (defun foo (barbaz) (setq bar))
7. Again with point after "bar", hit C-M-i
8. Emacs reports "no match" instead of completing to "barbaz"

This used to work as expected in Emacs 28, but not in 29, 30 or master.


Regards,

Eshel

Maybe it's worth bisecting this?
