Well, yes, maybe, but I would like to avoid this effort.

After reverting the mentioned commit, org-drill is working like expected again
and the function call:

(org-make-tags-matcher "")

evaluates to:

("" lambda (todo tags-list level)
  (and (member todo org-not-done-keywords) (and t t)))

In HEAD it evaluates to:

("" lambda (todo tags-list level)
  (and (member todo org-not-done-keywords) nil))

Hope that helps.  If not, I will go and make my homework with the ECM.

Best regards
