It seems, prefix argument works now. Let me remind that file name 
completion was working better before your change.

I have noticed a couple of error messages. Unsure what is going wrong, I 
hope, command to launch emacs is correct (-Q -L ~/src/org-mode/lisp 
test.org).

At startup:
Eager macro-expansion failure: (error "rx ‘not’ syntax error: (or 10 44)")

In response to M-x org-table-import:
rx-check-not: rx ‘not’ syntax error: (or 10 44)

I do not know opinion of Org maintainers. Personally I believe that org 
can take advantage of Emacs core features or of other packages if they 
are available and fallback to minimal implementation otherwise. Unsure 
whether borrowing code from pcsv can cause license issues. Current CSV 
parser is not perfect but it works reasonably well.
