I'm looking forward to doing a bit of testing on this patch. I think it is a really useful feature to get a bit more out of existing indexes.
I was about to test it tonight, but I'm having trouble getting the patch to compile... I'm really wondering which compiler you are using as it seems you're declaring your variables in some strange places.. See nodeSort.c line 101. These variables are declared after there has been an if statement in the same scope. That's not valid in C. (The patch did however apply without any complaints).
Here's a list of the errors I get when compiling with visual studios on windows.
