The commit subject is a bit weird in that it does not contain any verb,
it only postulates what happens after the change you do here. How about
"completion: complete options for git-bisect view"? You can then explain
why we only complete options, but not the actual subcommand itself in
the commit message a bit more in depth.

This part doesn't have a lot to do with the changes you're doing in this
commit. So it might've been better to add this explanation in the patch
where you introduced completion for "$term_good" and "$term_bad".
