Um...

It's not a bisect hazard, of course, but if you don't fold those
together, you might at least want to give the second one a different
commit summary... I hadn't been able to find an analogue of #init_path on
top of that either.
As it is, #init-user-pointers is fine (aside of that SNAFU with unfolded
pair of commits), and so's the contents of #init_path part following what
used to be #init-user-pointers, but it'll be an awful mess on merge in
the current shape.
I can sort it out myself, if you don't mind that; again, I'm OK with
the contents and I've no problem with doing reordering/folding.
