No more oops. —
GIT is immensely impressive. Sadly, Dominik Brodowski is even more impressive, and has a fix for the bug I was having fun bisecting sitting in his PCMCIA tree; note to self to next time mail the relevant maintainer and ask if they know anything about the bug you’re going to try and fix.
Here’s the git bisect visualisation letting me know which merge was responsible, which is where I decided to check out brodo’s tree. (Of course, I could also have continued the bisection down to the individual patch.)
