Reversing the change would probably not be a good idea. I
made this change (and I apologize for not mentioning it in
upgrade.txt) because with the '?' stuck on the first form
element would also have a '?' stuck in front of it (e.g.
'?:columns' instead of ':columns'). This would make us miss
one of the arguments (usually ':columns').

Anyway, I have fixes ready for upgrading.txt and page.html.
If you don't want to reverse the change, I'll check them in
to both maint-0.6 and HEAD.
