I don't understand why there is so much in this PR. Help me understand.

[joa-quim]

Neither do I. This bloody git is a complicated thing. I don't know where it got all those changes.

And another incomprehensible thing is that the changes to pscoast where applied to 5.4 I don't know how.

If you look at the top of the PR (below the title) it says that "joa-quim wants to merge 96 commits into master from 5.4". That means that all commits from master would be applied to the 5.4 branch, which is probably not what you want.

The 2 commits from Joaquim and 1 from Remko ended up in branch 5.4. I'm guessing Joaquim did a git checkout 5.4 and git merge master or something like that locally. There is no record of this on Github PRs.

The command for picking a single commit from one branch to another is git cherrypick. I'll try this out now and post back how it works.

As a rule, don't merge master into 5.4. Always make a branch starting from 5.4 and submit a PR through Github selecting 5.4 as the base.
