Two things:

 - My changes and your changes do not conflict - i was able to
   apply your patches on top of my changes.

 - I could have applied all three patches of yours but i only
   applied the first one because the second and third did not
   implement the feature you are trying to add in an adequate
   way.

Also, i do not 'request' things from you, i am not your boss. I 
review patches and i reject patches i find inadequate. You are
free to submit new versions - or you are free to not do so. If
you submit new versions i will review them too and will merge
them or tell why i didnt merge them.
