kdiff3 arguments order

[Yuri Nesterenko]

Colleagues,

moderately useful dry-run finding:
using kdiff3 as a merge tool for mercurial, you better wrap it in the script
like this ("merge = ~/bin/kdiff3.sh" in my .hgrc):

#!/bin/bash
/opt/kde3/bin/kdiff3 -o $1 $2 $1 $3 

This way, it will take common base of two revisions as a base 
(which is correct), will correctly merge different lines,
and will save the result in the right place.

Thanks,
-Yuri
