Thanks, @koobs.

One other note. When taking maintainer'ship or when combining multiple changes, land all changes that can be MFH'd first , and the version update separately.

This ensures ports in all branches have the same maintainer

one commit to update the MAINTAINER and bump up PORTREVISION, and MFH this commit.
then another commit for the version update and no MFH, right?

Yep, rule of thumb:

• Mergeable commits first
• Non mergeable commits last

Mergeable commits:

• Consistent metadata (maintainer, etc)
• Bugfixes
