As long as you’ve thought it over, I’m happy with it.  As you say, the
postimage matching without the preimage matching should be a rare
event.

FWIW what I was imagining was some structured binary format:

With A some long string, patch 1:

 A  --> AAA

Patch 2:

 AA --> AAA

Ideally one would want an attempt to apply patch 2 to result in a
conflict.  Probably that is far-fetched.
