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?

Cheers,
Michael
