Yes, apologies since I'm not exactly sure how to add text that would be taken
out in final patches. v2 fixes an issue with reconfigure breaking since it
assumed there was always a target (not true), I can't remember what v3 fixed, v4
fixed v2's fix since I used the wrong variable name. Perhaps I should write
diffs to patches assuming all the patches are in a single directory?
