Mercurial's undo is taking a snapshot of all the changed file's repo file length

"Trunactes"? That sounds very wrong... you mean replace with old
version? Anyway, what if the file has same length? It just doesn't make
much sense to me.
I believe this works because the files stored in a binary format that
appends new changesets onto the end. Thus, truncating the new stuff from
the end effectively removes the commit.
