Hi, I'm a bit afraid about this recet commit:

  http://github.com/tenderlove/nokogiri/commit/45c6d1d4902e100fecc3741985870aa4edda9a25
  "xpath methods can return things other than nodesets"

In my case I use Nokogiri in a server application which receives Xpath strings 
from remote clients and performs such Xpath operation within a XML document 
stored in the server.

However I do a strict pre-parsing of the Xpath string so it must have the form 
of a "typical" Xpath ("ns1:root/ns2:child/ns2:somenode[@name='lala']").

The server application expects to get a NodeSet after performing the Xpath 
operation and evaluates it (empty, number of entries....) by alwasying 
inspecting the NodeSet#size method.

Should I care about this new commit? Could occur that Xpath returns something 
but a NodeSet in my case?

Thanks.
