bug#33301: 27.0.50; broken elisp indentation for non-definition symbols starting with "def.."

[João Távora]

Hi maintainers,

This doesn't seem the correct indentation for the following elisp forms:

(let ((bla
       (ok))
      (defan
        (strange))))

(cond (bla
       ok)
      (defan
        strange))

...but that's the way Emacs -Q does it.  I'd be suprised if this weren't
a duplicate, but I thought I'd report it just in case.

Thanks,
João
