This commit also makes the halfop rules for +h/-h match the ones in U5:
Previously in 6.0.0 - 6.0.2 it was:
* halfops can set +h on others
* halfops cannot set -h on others
* halfops can set -h on themselves
Now in 6.0.3+ it matches 5.x behavior again:
* halfops cannot set -h or +h on others
* halfops can set -h on themselves
