Mercurial's undo is taking a snapshot of all the changed file's repo file length
at every commit or pull.  It just truncate the file to original size and undo 
is done.

"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.

Everything in Mercurial is an append-only log. A transaction journal
records the original length of each log so that it can be restored on
failure.
