You want this: ?
/* All signed integer elements in JSON arrays get stored into */
/* QInts when we convert to QObjects, so we can check them all */
...
I think this is quite annoying for refilling with emacs
Perhaps rather
/* All signed integer elements in JSON arrays get stored into
* QInts when we convert to QObjects, so we can check them all */
quite uglier to me, but I don't care
However, I'd prefer if either we have a common rule in qemu or we don't
bike-sched over that...
(even better would be to have this somehow automated with tools like
git-clang-format)
