If --detach comes from an alias, the user didn't go to the effort of
typing it. So there's a higher chance of the user wanting the
pedantically correct (or perfect) behaviour of completing all commits
rather than our too clever by half (or good) behaviour. However, I tend
to find that cutting down the number of completion matches where
possible is nearly always helpful.

Fair enough. I don't have any tag or group ordering styles for git
myself though I may have been put off trying on a couple of occasions
due to nested tag loops making it not entirely trivial.

Ok, patch below reverses the if.

Doesn't it need -b to create a new branch?

In such cases, compadd -x should be used for explanations instead of -X.
