I kind of agree with you, that svnmerge sometimes makes things more
complicated than they really are. But how come people can say svn is
easy when you have to read a 150 lines documents for such trivial things ?

Let's say "using" branches is a PITA in svn.

git tag my_tag_name # create a tag
git co -b work_branch # create a new branch work_branch
git merge branch1 # merge branch1
git log branch1..work_branch # log all revisions from branch1 to work_branch

Note that I have not yet mentioned the speed: doing the above in svn
takes like 1 minute or 2 for me, whereas it takes < 1s with git.

cheers,

David
