I don't know if they're all actually incorrect. Based on an non-obvious 
distinction - yes.

Since a commit message contains a summary, maybe a few headers, and a 
ChangeLog entry, it's fair to describe what a "ChangeLog entry" should 
contain.

Right, there's no separate name line in the ChangeLog entries inside 
commit messages. Updated.

This one actually seemed outdated. Removed.

This still applies. Even though it could say "in commit messages", this 
also emphasized the fact that the same non-sandardized references will 
appear in the ChangeLog file.

Still true, and I'm not sure how to rephrase this to refer to commit 
messages.
