I started getting/looking at hg a few days ago, mainly at the source 
only so that I likely miss some things...

Hmm. I'll need to further read the hg source to see how they do it. I 
now switched to defaulting to use the hg changes for normal changesets 
and the full manifest for merges. That's a huge boost already. Your 
approach sounds even better... so that I'll use it. :)

   bye, Rocco
