Well, for git and svn "revisions" are really "versions" of the complete tree, not changesets. Have messed around with hg lately? ;)

On the other hand, a commit that introduces a new version is the difference with respect to the previous "version".

Ususally it's clear what is meant, but you seem to mix both notions.

So, if v? denotes a version, then v4 is the result of all commits leading up to v4. It *is* v4. "squashing" applies only to commits ("changes").

In any case, Sverre's as well as my suggestions should do what you want. Why not try it out if you doubt it?
