That guarantees all of those patches will conflict and the engineers
will curse your name.  Don't do that, it's horrid.  What happens if
someone picks one patch, and then skips one, and uses the third?  What
would be the "version" then?

Just drop it entirely, it's useless.  You have the source, so you know
what changes are done, no need to try to match it up with a random
number.
