Is there some reason these patches (and the existing compact code in the
lib) is using fprintf and not the status callback function? Most places
we don't (yet) have logging callbacks, but here we do.

Nope. I simply wasn't aware of this infrastructure. I can put together a
patch to fix this.

test_expect_success executes "$2" ("notmuch compact" in this case)
do you mean to run notmuch 'compact twice' ?

Now do you mean to run 'notmuch search \*' twice ?

It's been a while but I suspect I just never cleaned up the patch after
coming to this realization. Anyways, it's fixed in the revised patch
coming shortly.
