[pacman-dev] xdelta support in pacman 3.x

[Dale Ogilvie]

Hello all,

I reckon it would be great to download only diffs for new package versions 
instead of the whole enchilada every time a buffer overflow exploit is fixed 
in kernel26. Building on Thikasabrik's good work on the forum (see 
http://bbs.archlinux.org/viewtopic.php?id=22872) I have come up with the 
attached patch for makepkg. 

FYI, I intend to look further into the pacman side of things next up. I hope I 
can make this thing work... Comments & suggestions are welcome...

Regards

Dale
