[pacman-dev] xdelta-ing in pacman 3.1

[Dale Ogilvie]

I for one would like to see this fly. Someone just bumped OpenOffice up a 
notch, hello Mr 158M download...

For me the xdeltas should just be created as far as possible "without 
maintainer intervention" and stored alongside the package. 

One could put a size saving threshold on the delta into makepkg, if the delta 
is over say 50% of the size of the total package, it doesn't get uploaded... 
Once pacman 3.1 gets into testing I'll look at the code again.

I've been running pacman with wget-xdelta.sh for some time now, its sad to see 
messages like these flash by...

Proceed with installation? [Y/n]
