3) Third time, to make sure I really did NOT forget to remove the -C
on the second run...
That third run will produce an error message about it being a "reversed
patch", and offer to back out the changes. If I get that, it means I
actually got it in the tree.
Apparently, step one is from getting a few bad patches or conflicting
patches (lesson: don't ask five people for comments on an article. You

Step 3 is because...uh... I'm a royal screwup sometimes. I've learned a
certain amount of fault-tollerance. 8)
Anyway, if you try to re-apply a patch (even better, if you attempt to
do it with a -C), it will let you know...so trying to do so is a decent
