Note: -d only works if the branch is considered "fully merged". You
need -D to override that check.

Also, it is revertable, sort of. If you know the commit ID it was, you
can:

$ git checkout 
$ git branch 
$ git checkout 

This will work as long as "git gc" hasn't been run since the delete. If
it's referenced from somewhere else then it will work even after
garbage collection.

Have a nice day,
